No, as it was to do with a change in the MinGW runtime system and not in R. Expecting to be able to use ^C as a Windows signal in a shell that is emulating Unix is I think unrealistic. ^C in Rterm does work in tcsh.exe, cmd.exe and various clones. It is becoming a mantra, but *** Cygwin is not Windows *** and R is a Windows and not Cygwin executable. People who want a Cygwin port of R perhaps should work on one .... -- Brian D.
