Strings as variable references in R

Question

R newbie question here. I have a list called dbdata. Normally I use it like this:

myresults <- rlm(V001 ~ V002+V003, data=dbdata)
         


        

Answer 1

You can create formulas based on strings with the reformulate function:

form <- reformulate(c(var2, var3), response = var1)
# V001 ~ V002 + V003

myresults <- rlm(form, data = dbdata)
