[R] foo.RData or foo.r?

[Adaikalavan RAMASAMY]

*.R is for the script file and is ASCII type.
*.Rdata (or sometimes *.rda) is the usual extension for R data and
contains binary information.

If you try to cat a *.Rdata file, you will end up with gibberish as it
is binary.

Try opening *.Rdata with emacs if you can. Emacs will recognise it as a
fundamental type and not as an ESS type. There might be ways to
associate Rdata files with ESS. But other people might not consider
reading your "*.Rdata" files.

Dear All,

I suspect this is kind of dumb, but when I was under the thrall of the
dark lord (read, using a W2K box), all my work in R files came out as
foo.RData. I moved on to GNU/Linux, and all the old .RData files keep on
working as they used. No problems in loading and stuff. But I use R from
the terminal. Assuming I decide to switch to emacs, do I need to save my
work as foo.r? what about my old files? shall I simply "mv" them to
foo.r? all in all, foo.Rdata and foo.r, does it make any difference?

Regards,

Federico
