[R] Rtools required

[Spencer Graves]

       I just encountered something that looks exactly like that with R 
4.0.0 and the latest RStudio AND with Rtools40 installed under Windows 
10 (AND some manual adjustment of the path to delete references to old 
versions of Rtools and make sure Rtools40 was there).


       I got around it by have Rtools40 installed AND running 
"install.packages('xmlw')" inside R 4.0.0 inside a CMD prompt.  That 
worked, even though the same command inside RStudio failed with:


WARNING:  Rtools is required to build an R package but no version of 
Rtools compatible with the currently running version of R was found.  
Note that the following incompatible version(s) of Rtools were found:

       - Rtools 3.5 (installed at C:\Rtools).


       I got this message after deleting references to C:\Rtools from 
the path and rebooting.


*** I BELIEVE YOU NEED Rtools40 installed, because binaries for some 
packages are not (yet) available for R 4.0.0.


       Hope this helps.
