In sas, you can create a variable label with the label statement. you can use this statement to assign one or more labels using 3 methods, namely a sas data step, the proc sql procedure, and the proc datasets procedure. the exact syntax of the label statement depends on the method of choice.

Solved Reading In Data Sets With Spaces In Variable Labels Sas 9 4 Vs Here are the three most common ways to subset a dataset in sas: method 1: choose which columns to keep. set original data; keep var1 var3; run; method 2: choose which columns to drop. set original data; drop var4; run; method 3: choose which rows to keep based on condition. set original data; if var1 < 25 then delete; run;. You can use the label function in sas to provide label names to variables in a dataset. the following example shows how to use this function in practice. suppose we create the following dataset in sas: data data1; input id $ x y; datalines; run; *view contents of dataset* proc contents data=data1; run;. In theory, there could be sas® syntax to set a variable label to the value of another variable. it might look like call setlabel( varname, varlabel). since this syntax does not exist (yet), programmers have developed a variety of techniques for labeling. First, you must create the label formats with proc format using a value statement. next, you attach the label format to the variable with a format statement. this format statement can be used in either proc or data steps. an example of the proc format step for creating the value formats, forgnf and $makef follows. value forgnf 0="domestic".

If you want to display the original data values rather than format labels, you can use a format statement that specifies one or more variables without using any format names ä. By using the datasets procedure, you can change a variable's format with the modify statement and its subordinate format statement. you can change a variable's format either to a sas format or to a format that you have defined and stored, or you can remove a format. here is the syntax for these statements:. This module demonstrates how to select variables using the keep and drop statements, using keep and drop data step options records, and using the subsetting if and delete statement (s). While we use variable names when we are writing sas programs to specify which variables are to be processed, we use variable labels in our output. variable names are often short and cryptic, while variable labels can include spaces and special characters, allowing them to be much more expressive.
