[R-pkg-devel] Failed: Future File Timestamp Check

[Jeff Newmiller]

Packages are supposed to work when mounted in a read-only filesystem... using writeLines seems like a very bad idea since you can't assume the package install is writeable when it is run, and running code from tmp is a security hole.

If you absolutely cannot think of a way around running code from generated files, then maybe you should use textConnection to run from internal RAM.
