How do you rename a variable name with space in SAS?
rename var1 = ‘variable one’n; run; The options validvarname=any; tells SAS to allow you to have variable name begin with or contain spaces, special characters or numbers. Additionally, we need to put variable name having spaces in quotes followed by the letter n.
How do you rename variables in SAS?
You rename a SAS variable with the RENAME option. The RENAME option is a data set option which enables you to change the name of a variable. First of all, you define the old variable name, then an equal sign, and finally the new variable name. You can rename one or more variables with one RENAME option.
Is space allowed in variable name?
Variable names cannot contain spaces.
What is Vname SAS?
VNAME returns the name of the specified variable. Related functions return the value of other variable attributes such as the variable label, informat, and format, among others. For a complete list, see the Variable Information functions in SAS Functions and CALL Routines by Category.
How do you reference a variable in SAS?
After a macro variable is created, you typically use the variable by referencing it with an ampersand preceding its name (&variable-name), which is called a macro variable reference. These references perform symbolic substitutions when they resolve to their value. You can use these references anywhere in a SAS program.
How do you rename a column in SAS?
There may be occasions in which you want to change some of the variable names in your SAS data set. To do so, you’ll want to use the RENAME= option. As its name suggests, the RENAME= option allows you to change the variable names within a SAS data set. RENAME = (old1=new1 old2=new2 ….
Why are spaces not allowed in variable names?
The reasons that spaces were historically disallowed in variable names is that it tends to introduce ambiguity into language grammars, where a space separating two identifiers may be meaningful (e.g. Haskell).
Are variable names case sensitive Can you use spaces in variable names?
Specifically, spaces are not permitted in the variable names, as variable name must be a single word. Variable name may not start with a digit or underscore, and may not end with an underscore.
How do you rename two variables in SAS?
To do so, you’ll want to use the RENAME= option. As its name suggests, the RENAME= option allows you to change the variable names within a SAS data set. RENAME = (old1=new1 old2=new2 …. oldk=newk);
What is Vname?
VNAME returns the name of the specified variable. If the name is a known variable name, the function returns that name.
How does the rename statement in SAS work?
Details The RENAME statement allows you to change the names of one or more variables, variables in a list, or a combination of variables and variable lists. The new variable names are written to the output data set only. Use the old variable names in programming statements for the current DATA step. RENAME applies to all output data sets.
When do you need spaces in a variable name in SAS?
To read them in SAS, we need to know how to read variables having spaces in their names. It is also required when we transpose our variables and the variable whose values name the transposed variables in the output data set contains special characters.
When do you Drop a variable in SAS?
If the option is used on an input data set, the variable is dropped, kept, or renamed before it is read into the program data vector. If used on an output data set, the data set option is applied as the variable is written to the new SAS data set.
How to rename variables in a programming statement?
The RENAME= data set option allows you to specify the variables you want to rename for each input or output data set. Use it in input data sets to rename variables before processing. If you use the RENAME= data set option in an output data set, you must continue to use the old variable names in programming statements for the current DATA step.
