Clarification. R does that automatically _for paths used by R_ (including, on
my system, the path to command in system(command) ) but NOT for path or file
arguments supplied to that system command. So R correctly runs cmd.exe when
specified as system("c:/windows/system32/cmd.exe") but if you wanted to supply
a path as an argument R does not know that the argument is a path and wisely
doesn't treat it as one.
So (on win XP and using R 2.15.3)
system("c:\\windows\\system32\\cmd /c dir c:\\windows\\system32\\d*.*",
intern=T)
#and
system("c:/windows/system32/cmd /c dir c:\\windows\\system32\\d*.*", intern=T)
#both work but
system("c:/windows/system32/cmd /c dir c:/windows/system32/d*.*", intern=T)
#does not
