Hello everyone,
I want rename multiple varaibles (they have common begin characters var_)in data three, but not work,please help.
data one;
var_1=1;var_2=2;var_3=3;var_4=4; var5=5;output;
run;
data two;
set one;
rename var_3=var_3_new;
*rename var_:=varname(var_: )||_new;
run;
data three;
set one;
rename var_:=varname(var_: )||_new;/*this not work*/
run;
Thanks!
The rename only takes text, you can't use functions like that. You need to list all out.
If if you have a series with common prefix you can do the following:
rename x1-x5 = new_x1-new_x5;
Use prefixes rather than suffixes to make your life easier.
You could create a map file to describe how to rename these variables. data one; var_1=1;var_2=2;var_3=3;var_4=4; var5=5;output; run; proc transpose data=one(obs=0) out=temp; var _all_; run; data temp; set temp; new=catx('_',_name_,'new'); run; data _null_; set temp end=last; if _n_=1 then call execute('proc datasets lib=work nolist nodetails;modify one;rename '); call execute(catx('=',_name_,new)); if last then call execute(';quit;'); run;
