CRAN demands re: writing files #36
Description
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.
Limited exceptions may be allowed in interactive sessions if the package obtains confirmation from the user.
This is from the cran demands for submitted packages. I fear our design function does not adhere to this.
