[R] R_LIBS_USER not in libPaths

I have not intentionally set R_LIBS_USER. I looked for an Renviron.site
file but did not see it in R/etc or my home directory. The strange part is
that if I print Sud.getenv I see a value for R_LIBS_USER. However, this
directory is not showing under libPaths.

I though .libPaths should contain R_LIBS_USER.

I also noticed that R related variables are not in the system or user
variables because I dont see them when I type SET from the Windows Command
line. So a related question is where does R get the system variables
(e.g., R_LIBS_USER,
R_HOME) if I dont see a Renviron.site file. Thanks

I'm not sure I follow what.the problem is. Are you trying to
set R_LIBS_USER but R does not acknowledge it, or do you observe something
in R that you didn't expect to be there and you are trying to figure out
why that is / where that happens?
