I used Learn how use the CAT functions in SAS to join values from multiple variables into a single value. Convert multiple variables from char to numeric. In SPSS, i know we can recode variables easily using following command: recode x (1=2) (else=copy). However, I keep recieving the message saying variable uninitialized. Below is my code in SAS Studio . " Character values The GLMMOD procedure can create dummy variables for each categorical variable. ] other ='NA' ; run; /* if only for display purposes */ proc print data=df1; format a b c num2char. BTW. There are a few tricks that are worth noticing. Please refer to my other post in which I have explained my data structure problem.

You could use a format for recoding and if only required for display (print) purposes then even apply it directly to the numerical variables. SAS Training: Just a Click Away I need to recode a set of 8 variables into a single variable, such that if all 8 are missing then the new variable is missing, but if even one of the variable = '1' then the new variable = '1'; else the new variable = '0'. Once the variable is created there really isn't any other approach than either an input or put to a new variable. Getting Started; Community Memo; All Things Community; SAS Customer Recognition Awards (2024) Recode a Variable. Home; Welcome. Copy and paste this code onto the Program tab. The code you have is fine, just add the following statement right before the first if. In many of our datasets, we already have STHA defned numerically (which we can format) but the Macro merges on a character variable Create a format. Getting Started; Learn how use the CAT functions in SAS to join values from multiple variables into a single value. Ready to level-up your skills? Creating new variable and Recoding SAS. ); run; The data are purely numbers (ie 1, 20, 25, 100, 250, etc. If the variable is coded as missing SAS will be able to deal with it as missing - which usually means exclude the value. Precisely, that invokes heavy macro processor work Can you please recode this variable for me; Married =1 and not married =2. Ready to level-up your skills? Welcome to the SAS forum. This new variable is added to the current data set. Viewed 376 times 2 . You can easily check that the length of the inter variable is 2. with character variables as 'I000' will usually come up as less than 'I09'. z; c=1; output; a = 1; b=1; c=. Are you wanting a numeric value or are you asking for IF/Then/Else type code to reassign values of the existing variable? I ask because a SAS Format is a typical way to change I need help creating a new binary variable from an existing data set. 7: Task Reference Guide documentation. For example, the expression The PUT functions PUT(), PUTN(), and PUTC(), are the SAS conventional methods for recasting or recoding values. ; output; run; proc format; value num2char low-high =[f16. PUTN() and PUTC() (for character values) allow the format to be provided dynamically, as you require in this case. That is, if CODE has a value of 1 (numeric) it cannot be given a value of “A6037” (character). In one of the datasets two variables have character format, however in the other dataset all variables are numeric. length REF_COMP_1st_REC $ 2; Otherwise, SAS uses the length of the variable the first time it is assigned, which is one character. If you want to adjust the display format of the output variable, use the FORMAT statement. d informat. ); run; then I started to use the approach you suggested: recode values in a character variable based on another character variable's value in sas Recode a Variable SAS/LAB software provides facilities for creating a new variable that is a recoding of an existing variable in the same data set. 3 Update 3 (8. is not converted to a blank value, the dot is remaining there, and i found it very annoying, because pulsechar is not a real character I am new to SAS EG 7. Modified 7 years, 2 months ago. This method of recoding enables you to assign a value of the new variable for each particular value of the old variable. 4 and I'm trying to recode a variable called PHQ_9_Severity into "Normal" "Mild" "Moderate" Community. 1 Like 12 REPLIES 12. There are several ways to recode data using SAS(r) software. You'll need to process or clean the data ahead of time or use the RECODE task to recode them. Suppose we have the following dataset in SAS that shows the total sales made by some store during 10 consecutive days: But then you try to assign AGECAT="0-19", which is a character string. For example, the following statement sets the day of departure based on the number of days in the tour. so I copied and pasted each value of the variable from a PROC FREQ to get something like the below Some char variable values not recoding to indicator variables Posted 10-08-2024 06:51 AM (1420 views) I am creating indicator variables for character variables with a dataset imported from excel. The one getting missed is a variation of an Some char variable values not recoding to indicator variables Posted 10-08-2024 06:51 AM (1706 views) I am creating indicator variables for character variables with a dataset imported from excel. ” Additionally, this example will deal with a single variable only. com The INPUT and PUT functions convert values for a variable from character to numeric, and from numeric to character. The target is Y with levels 0 and 1, and there are four predictors X1-X4. data work. Character variables can be used in declarative statements, comparison statements, or assignment statements where they can be manipulated to create new character variables. SAS Training: Just a Click Away. Muchas Gracias. That is, character values must be specified in the same case in which they appear in the data set. and 8. 1 Like SASKiwi. ; SUBSCRIPT is the number of values the array is going to store. sas. | Miami University - Oxford | Sas code examples demonstrating various data manipulation techniques, including recoding missing values using . Calcite | Level 5. These are default assignments SAS will give on initialization. I am trying to use ARRAY to recode a series character variables VAR1-VAR5 into a series of numeric variables nVAR1-nVAR5 and a series of character variable rVAR1-rVAR5. Modified 5 years, 9 months ago. And for your new variables if you name an array like: Array newq(10) that will create 10 numeric Hello sbjwhl, Thank you for the help, but I don't know why It doesn't work.
