Thanks for replying.
My problem is that i have say 50 input files, that i wanted to run a
particular command on, get 50 output files, and then when i close R, have
them in my directory?
so for example if i say:
>R
>library(MASS)
>list.files(pattern = ".out")
>sapply(list.files(pattern = *.out"), function(x) wilcox.test ( ... ) )
<<<send each output to a different file, and save it in such a way that
when i close R the outputs are still there>>>
i thought this might be easier in a shell way?
