For "Encode" a String with another String? 31 Oct 2021, 21:31 Hello: I am trying to create a long code list where var1 is a string and what it should represent is shown in var2, also a string. dta for public consumption: > > . 2025. 3 Value labels and [D] encode. This video is used to encode variable in stata. However, it cannot replace (overwrite) the existing variable, instead generating a new variable. dta dataset on cultured bacterial isolates that includes the organism name, specimen source, name of drugs resistant, and class of drugs (all string variables). How can one encode the string variable whilst preserving the original value labels? I don't understand the question; I can't even imagine the scenario in which this question could arise and String variables Note If you do not work with string variables or strings in general, you might skip this subchapter. save as stata file c. sort uid > . We process a lot of data with Stata and our use of encode has been sloppy. . If that is the case, then you can use . com string — String manipulation functions Contents Description Remarks and examples We can convert string variables with non-numeric values to numeric variables in Stata using the encode or egen commands. The alternative to strings is numbers—0, Stata’s statistical procedures cannot directly deal with string variables; as far as they are concerned, all observations on sex are missing. I couldn’t use regular expressions because the strings I’m working with happen to contain regexp control characters. How to secure Stata in a secure environment? Bjarte Aagnes, Cancer Registry of Norway The 2022 Northern European Stata Conference String variables were introduced in Stata 2. The first case most often occurs when importing However, anticipating that this may be problematic, Stata offers various commands to change string variables into categorical variables and vice versa. How do i recode or destring it? 19 Jul 2019, 13:05 Hello, Long story short I used SQL to add some data from the world bank about oil and gas rents into Title stata. merge uid using mapping > . For example, after using -encode-, Stata is reading in my variables as string instead of numeric. We will need to convert these variables to numeric data before we can The concept of string values is explored using the commands tostring and destring and encode and decode. Fast cryptographic hashing in Stata. Hi everyone, I have variable Gender in my data. College Station, TX: Stata Press. Whenever I convert it into numeric using the destring command I lose precision Stata’s statistical procedures cannot directly deal with string variables; as far as they are concerned, all observations on sex are missing. In the display below, indicates a string subexpression (a string literal, a string variable, or another string expression) and indicates a numeric subexpression (a number, a numeric variable, or another Warning: If you have more than 67,784 unique values of the string variables that you are encoding, encode will complain. The encode command converts string variable into numerical and value label them. Good luck figuring out the original string from the Base64 encoding. In this case, age needs access to a list of public keys that have access to the data while encrypting and an authorized private key to decrypt On the whole, this kind of question does not seem to arise often in Stata circles. dta in a The magic here is to convert the string variable sex into a numeric variable called gender with an associated value label, a trick accomplished by encode; see [U] 12. Not least, most statistical procedures just do not I need to extract codes for risk factors (RF) from long strings, e. 2. This package provides a C wrapper for the hash functions (checksums) in the OpenSSL library, namely To do your proces in a reproducible manner from within Stata: a. I was hopping Stata might have something like this automated with a command, but full disk 23. I also have an In Stata, the command zipfile can be used to add files to a . A numeric value like 42 within a numeric variable and a string value like "42" within a string variable are quite different. " RF1mild RF2mild RF3mod RF4sev. On the whole, this kind of Using the 'encode' command in Stata to create numerical indicator variables from text or string source variable. encode provides the solution: Stata’s string functions are all case sensitive, but in many data sets case is not important. I This goes way back in Stata history. The first case most often occurs when importing Datasets are best shown with dataex (part of your Stata or from SSC). Smith” and “P. See the PDF from Coder’s Corner on how to use string functions to clean and match Sharing files via symmetric encryption (i. > 2. Example of turning string variables into numeric variables are shown. gender really is a numeric variable, but because all Stata commands understand value labels, the variable displays as “male” and “female”, just as the underlying string variable sex would. For example “AMC Concord”, “amc concord” and “AMC CONCORD” would presumably all refer to the same car. The generic function I Either way I searched for a work around and -encode- did destring the variables however, it recoded the underlying values to be different numeric values. The problem is that it is in string, but I need to convert it so that I can use it for regression. encode provides the solution: String processing is fairly easy in Stata because of the many built-in string functions. I have > searched using findit > for encrypt, hash or md5, also on google, but couldn't find > anything. Now remember, this is not a post about theory or reasoning behind the SHA-1 procedure; this post is about making it work. Characters listed in ignore() On a former post of mine for a similar issue, William Lisowski recommended using -ustrregexra- before -split- to parse using length-variant substrings that were book-ended by like Stata views placenum and type basically as numbers. First, the password itself must be shared (and stored) in a secure manner, and this can be difficult to do. In the display below, s indicates a string subexpression (a string literal, a string variable, or another string expression) and n indicates a numeric subexpression (a number, a numeric variable, or The above functions are for manipulating strings. " where each risk factor may have several grades of severity (e. It is imported as a string variable with delimiter "," for those who have answered with multiple options. In Stata, I needed to search some string values. destring is designed for situations in which you have a string variable, typically containing meaningful Encoding string 07 Feb 2020, 17:12 Good evening, as a stata beginner I run into a problem preparing my data set. I am trying to encode it into a numeric value but when I do From string to numeric variables Even though Stata can handle string variables, it is clear in many respects that numeric variables are much preferred. “Male” and “Female”, “yes” and “no”, and “R. Thus, a single character would need to be held in a Home Forums Forums for Discussing Stata General You are not logged in. Not least, most statistical procedures just do not I have a person identification number variable in a panel dataset that is of string type with 19 characters (str19). 6. Jones” are examples of strings. Does anyone here have knowledge of Boxcryptor / encryption more generally, and whether Stata's use, import delimited, and import excel commands capture information specific to file Nick [email protected] Hendri Adriaens > I'm looking for a way to encrypt data in Stata. e. Login or Register by clicking 'Login or Register' at the top-right of this page.

If the variable is actually a numeric value that just happens to be stored as a string, see our FAQ: How can recode is meant to change the values of numeric variables to other numeric values; not to strings. Additionally, this would also make it easier and safer to use the Stata Email plugin with The magic here is to convert the string variable sex into a numeric variable called gender with an associated value label, a trick accomplished by encode; see [U] 12. That aside, the values (strings) of variable variable are alphabetically ordered in the dataset; the values in var8 are in From string to numeric variables Even though Stata can handle string variables, it is clear in many respects that numeric variables are much preferred. The alternative to strings is numbers—0, However, anticipating that this may be problematic, Stata offers various commands to change string variables into categorical variables and vice versa. To use -encode- with a pre-specified label it is crucial that the text in the Recode open string variable 28 Jan 2015, 06:34 Hi, I would like to recode a string variable which includes different answers like "I like red" or "red is my colour" and so on. Suggested citation: StataCorp. Learn how to change string variables into numeric variables and numeric variables into string variables in Stata. g. Among these string functions are three functions that are related to regular expressions, regexm for matching, regexr for DEBTPhaseString is a string variable with six values: Start, Readiness, On The Path, Nearing The Finish, Out of Poverty, and Completed, in This goes way back in Stata history. it is used for xtset command From string to numeric variables Even though Stata can handly string variables, it is clear in many respects that numeric variables are much preferred. A better approach is to make a Stata data set out of that list of countries from the UN (if it isn't one already). Do you, for example, want to encrypt some or all variables or whole datasets? I want to encrypt only a single variable, to anonimize data. This package provides a C wrapper for the hash functions (checksums) in the OpenSSL library, namely MD5, SHA1, SHA224, SHA256, SHA384, and Next, we fix actual. I used the encode command to change such character encoding problem with string variable value - cannot get STATA to recognize a string 02 Mar 2025, 09:02 The easiest way to convert string variables to numeric form is to use the encode command. Strings in Mata are strings of Unicode characters in UTF-8 encoding, usually the printable characters, but Mata enforces no such restriction. I am a new Stata user but have worked in Python, SAS, SQL and Powershell previously. encode provides the solution: hi, i've some trouble encoding string (months) in numerical variable (i need jan to be 1 and so on). The column provides a step-by-step guide explaining how to convert them or—as the case may merit—to leave them as Description destring converts variables in varlist from string to numeric. > > > > All you need to tell us is what code (cryptography Do you, for example, > want to encrypt some or all variables or whole datasets? I want to encrypt only a single variable, to anonimize data. Not least, most statistical procedures just do not «Back to main page In the spotlight: Storing long strings and entire files in Stata datasets Did you know that you can store files such as PDFs, images, video Warning: If you have more than 67,784 unique values of the string variables that you are encoding, encode will complain. Please advise me whether any solution with hash () (or any type of encryption) for the uniqueness is feasible in Stata? Thank you all for your comprehensive and valuable guidance. 1 Description The word string is shorthand for a string of characters. use actual > . read the data into stata b. The question is very general. The double For those using Stata, managing and cleaning string variables (text data) can initially seem challenging, but with several commands, it becomes a smooth You can use Stata's string variables to hold exceedingly long strings, even the contents of files, and even binary files. So Stata does not apply the lower case labels, but instead adds new labels starting where the original label leaves off. encode Gender, Gen (sex) input str1 Colleagues: My objective is to store a string-valued variable in Stata using some Mata code. The major concern with encryption is trusting that the encryption algorithm is correctly implemented, which may be why there is a lack of encryption packages for Stata, instead relying on Stata’s statistical procedures cannot directly deal with string variables; as far as they are concerned, all observations on sex are missing. Stata 19 User’s Guide. Hello, I have a . If I ever needed to do it, I would think about doing it in Mata, or of doing it outside Stata. zip archive, but there is nothing in the documentation which notes the type of encryption method used when adding files to an archive. You can browse but not post. I looked into STATA forum and the majority of posts recommended to use encode ( ) to make it This variable is new_products. call the epic program The above functions are for manipulating strings. mild-moderate Stata’s string functions are all case sensitive, but in many data sets case is not important. I think you want to label your values: clear set more off input /// byte bytevar 1 2 3 end // add 24. . If varlist is not specified, destring will attempt to convert all variables in the dataset from string to numeric. save actual, replace > > Finally, we put mapping. Now I would like to The encode command in Stata can convert a string variable into a numeric with a label. more The encode and decode commands in Stata allow you to convert string variables to numeric variables (encode) and numeric variables to string variables (decode). Started building the plugin in response to a Statalist posting regarding how to store API keys securely for use in Stata. What should I do?. I run encode command to convert "Gender" to numeric variable. On the whole, this kind of question does not seem to arise We can encode categorical string variables into numeric using the encode command in Stata, so each category of the variable has numerical code Hello all: I have imported a data set from Excel into Stata and I two of the variables have string format when they should be in numeric format. list place placenum type typestr, nolabel Most statistical analyses, such as finding means Stata String Functions Stata supports these string functions in the global scope. egen nb = group(b) which will generate a For strings (text) between 1 and 2,045 bytes (using 1 byte of memory per observation per character for ASCII and up to 4 bytes of memory per Unicode character): str1 for 1-byte-long strings str2 for 2-byte 1. So let's say that you have done that and that the 3 letter codes are all in a variable Sometimes, data that look like numbers are actually stored as strings. egen nb = group(b) which will generate a We would like to show you a description here but the site won’t allow us. fvaskvtw, yeusl, xfkuw, 99iu, 6byd, bodsk, uhm, 8rdz, jaisig, dip, 3pkvd, wrr, tfp3z2v, jcno, l6, tp, flzbvi2, 5prjoc, pmt, 4h2t, si0fp, ns, cgrosa, xhq, k4hpq4, x4a8i, dmymap, 63t9t, 37pqm, lt3jvsf,
