Shubha,

I don't believe there is an R equivalent to the SAS RETAIN keyword.  This is because R does not make the same kind of distinction between variables read from data files and those created by programming statements.  R is not SAS and you will be most successful using R if you don't try to force SAS solutions into it.

If you could give an example of some R code that you think requires the equivalent of RETAIN, I am sure someone on the list will be able to help with an appropriate R solution.
