Thanks for the update. I saw that http://cran.r-project.org/bin/windows/Rtools/VERSION.txt had the following contents: Rtools version 2.15.0.1911 So I downloaded Rtools215.exe but when I installed it, the VERSION.txt that was extracted read: Rtools version 2.15.0.1908 ...which is the same version I previously had installed. Has the new version not propagated yet or is there some other issue?
