I'm having problems with system(wait = FALSE) with R 2.12.1 (both i386 and x64 versions) on a 64-bit Windows 7 machine.
This is as expected: print(system("cmd /c dir", wait = TRUE)) This fails: print(system("cmd /c dir", wait = FALSE)) I did not see this with 2.12.0, and things seem to work fine with R 2.12.1 on a 32-bit XP machine. Can anybody else confirm what I'm seeing here?
