Hello,
My R package has a function with an argument to specify whether numerical
results should be outputted to a CSV file.
CRAN policy stipulates verbatim that
Packages should not write in the user’s home filespace (including
clipboards), nor anywhere else on the file system apart from the R
session’s temporary directory (or during installation in the location
pointed to by TMPDIR: and such usage should be cleaned up). Installing into
the system’s R installation (e.g., scripts to its bin directory) is not
allowed.
I know I should use tempdir() within my package function, but I've not seen
any examples on how this is best done within existing R packages.
Within my package documentation examples for my function, I have the lines:
\dontshow{.oldwd <- setwd(tempdir())}
... some R code ...
\dontshow{setwd(.oldwd)}
but I have been informed that this is not the accepted way.
Any ideas from the community on how do do this properly?
Thanks for the help!
Cheers,
Jarrett
