Which program? Emacs? If you've installed R, you can read a txt file
of R code into your R session with 

source("/path/if/any/file.R")

not sure what you mean. It makes sense to save files with R commands
with the ".R" extension, but AFAIK it's not obligatory.

If you don't have ess, I think you can get that, too, with "aptitude
install ess".

Then, in Emacs, you can open R with M-x R. You can now copy&paste
(kill&yank) R code from your text file to the R buffer; alternatively
there are special commands available, look at the menu in Emacs. If
you have Emacs anyway, ESS is much more convenient than running from
the console.
