Installing a package involves running several R subprocesses, each of
which is running that .Rprofile. You may be able to stop the infinite
recursion by setting an environment variable that subprocesses can
check. E.g. replace
install_github("xxx/yyy")
with
if (Sys.getenv("INSTALLING_FROM_GITHUB", unset="no") == "no") {
Sys.setenv(INSTALLING_FROM_GITHUB="yes")
install_github("xxx/yyy")
}
[This is totally untested.]
