R devel - Apr 2014 - Problem with Renaming R object

Hi,

I have a problem in renaming R object and saving them within a loop. For ex:

for (i in 1:length(all_files))
        {
            uncov_GR <- "variable created in loop"
            filename <- paste0(sample_name[[i]],"_uncov",
".Rdata"))
            save(uncov_GR,file=filename)
        }

Within the above short code (out of a long program), I want to change the
name of "uncov_GR" variable to the file name and save it by same file
name.
But I am unable to come up with any solution to do so.

I tried something like the code below:

for (i in 1:length(all_files))
        {
            uncov_GR <- "variable created in loop"
            filename <- paste0(sample_name[[i]],"_uncov",
".Rdata"))
           Objectout <- paste0(sample_name[[i]],"_uncov")
           assign(Objectout, uncov_GR)
           save(Objectout,file=filename) ### problem still persists with
saving
        }

Here I am able to make a copy of uncov_GR but I am unable to save the
object again with the same filename. Any suggestions in this regard would
be highly appreciated.

Thanks.

Regards,
Kamal

This is not really a question for r-devel, but basically you should use
saveRDS/readRDS rather than save/load.

save(list = Objectout, file = filename)
