Thanks John. Where is file .Renviron located? It must be a hidden file.
I cannot find it.

Dear Steven,
Did you follow the instruction on the Rtools webpage to add
PATH="${RTOOLS40_HOME}\usr\bin;${PATH}"
to your .Renviron file?
I hope this helps,
John

Dear All
I updated to R-4.0.0. and also installed the latest Rtools 4.0 (to now
the new default folder c:\rtools40). While compiling a package (binary)
I received the follow marning message saying Rtools is required. Any
clues? Thanks.
