All,I had a simple function call I used to open up a dos shell running R under Win XP: system("cmd.exe", wait=FALSE, invisible=FALSE). This does not work with R 2.12.1 - I get a window that briefly flashes open but then disappears. Does anyone know the method to open a DOS command window in running R with Win XP? Thank you.
This is a new bug in 2.12.1, which I am about to fix in R-patched. The problem was that it was passing a null input stream to cmd.exe, which saw an immediate EOF, and quit. A similar thing happened in Rterm, where system("cmd") should drop into a command shell in the same window, but it would immediately exit.
