[R] Store filename

[Daniel Folkinshteyn]

well, where are you getting the filename in the first place? are you 
looping over a list of filenames that comes from somewhere?

generally, for concatenating strings, look at function 'paste':
write.table(myoutput, paste(myfilename,"_out.txt", sep=''),sep="\t")
