How do I use a macro variable in R? (Similar to %LET in SAS)

Question

How do I assign a macro variable in R?

In SAS, I would use the following code

%LET DEPVAR = sales_ind

PROC REG DATA=mydata;
MODEL &DEPVAR = VAR1         


        

Answer 1

how about this:

reg<-lm(formula(paste(depvar ,'~  var1 + var2')), data=mydata)
