It turns out it was fairly easy to make ESS work in Cygwin Emacs with R built for Windows. The issue was of course path names. I attach a patch that works for me.
Let me explain that I am using a company-provided and managed laptop and I have no choice but to run Windows. I am familiar with a number of Unix/Linux -like environments for Windows (Cygwin, MSYS, WSL). I have tried them all over a period of years. I use R primarily as a means for presenting data. It is not the main thrust of my work. Having spent considerable time making this laptop a comfortable working environment I am loathe to switch. ______________________________________________ ESS-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/ess-help
