.Rprofile with devtools::install_github() loops
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.]

I have created a very simple package on GitHub and want my machines (other than the one that built it) to load it when they start R using devtools::install_github()
The install_github() call works fine from the console but when I put it in my .Rprofile it just loops on restarting R. I _think_ it may be that devtools::install_github()
is restarting the session as I found one thing on the web suggesting that may be the case. However, I think if it were the case it would be documented and I'd find
far more about that.
OK. So my .Rprofile is:
print("This is a message from /home/chris/.Renviron: hello Chris!")
.First <- function(){
devtools::install_github("xxxx/yyyy")
}
print("OK, off you go!")
I have obscured my package to protect my blushes but I get the same behaviour with r-lib/devtools and, as I say, my little package loads OK from the console.
You can see I tried wrapping it in a .First() function but that didn't change anything.
True both on a Linux machine and a Windows machine.
OK. Anyone save me from more dents in the wall and frontal lobe damage?!
TIA,
Chris
