It is a good sign. Your Rtools43 installation is working, but R for
some reason doesn't know about it.
What is the value of Sys.getenv('PATH'), Sys.which('make'),
Sys.which('gcc') inside a running R session? Presumably, if PATH
starts with something like
C:/rtools43/x86_64-w64-mingw32.static.posix/bin;C:/rtools43/usr/bin;
...then both Make and the compiler should be available to R. If it
doesn't, it's worth trying to prepend it there.
