[R] Save output
Dear R-Mastermind Within a while or a for-loop, is there a way that I can save to disk the results of the previous calculations at the end of each loop with filenames called file01.Rdata, file02.Rdata etc? So far, I have tried to write the outcome of each loop in a 3 dimensional array and saved it just once after the loop. Or is there another way so that I can keep the resulting matrix of every step in the loop?

as a toy example :
for (i in 1:nbfiles)
{
fullname = paste(myfile_,i, sep=);
write.table(intable, fullname);
}
see
?paste
hih

Re: [R] Save output
I think this is what you're looking for: file_name_root = myfile for(i in 1:10) result- of_some_function out_file-paste(file_name_root, i, .txt, sep = ) write.table(result, file = out_file) } the above code produces 10 files (myfile1.txt to myfile10.txt), each containing whatever was calculated on that loop. If you have loops within loops and you want to write during the innermost loop, remember to take this into account like so: file_name_root = myfile for (i in 1:10) for(q in 1:10) result- of_some_function out_file-paste(file_name_root, i, q, .txt, sep = ) write.table(result, file = out_file) } } That way, when i iterates and when q resets to 1, you don't write over your previous output.

?save
?sprintf
for(i in 1:12){
tmp - rnorm(10) # change it with your computations
save(tmp, file=sprintf('file%02d.RData',i))
}
