You probably need to ask this on a RStudio forum but my guess is it is just a little 'refinement' that the RStudio people added. Similar in concept o the the matching "".

Really? write.csv(data,?/home/data.csv?) works for me in Rstudio, ESS,
Terminal, Rscript etc.

Well, actually I misspoke. I don't actually have permission to write
to "/home" on my system. But

write.csv(data, "~/data.csv")

works.

Subject: [R] write.csv file= question

Hello,

I have a quick question about the ?file=? specification for the command
write.csv.    When I run this command in Rstudio I do not need the
?file=? specified.  For example the below command works just fine.

write.csv(data,?/home/data.csv?)

However when I am running an Rscript from the terminal and putting it in
the background I need to specify ?file=?.  So for the example above I
need to instead have

write.csv(data,file=?/home/data.csv?)

Any ideas why this is the case?  Writing file= isn?t a problem, just
trying to get an idea of how R works better.

Thanks!
