Unfortunately, no. .Platform$file.sep on a windows box is the "/". For this DOS program it needs to be the "classic" backslash.
Ok, we'll hack this a bit (query the platform and test if it is windows), but now I'm running into escape character problems. Given: files1="*.las" files1_formatted=file.path(getwd(),files1) files1_formatted [1] "X:/pathto/*.las" I want files1_formatted to read: "X:\pathto\*.las" Using: sub("/","\",files1_formatted) Doesn't work (in fact, its not a complete statement -- I assume since its waiting for something to follow the / ). What's the trick with this? --j On Tue, Jun 28, 2011 at 11:05 PM, Berend Hasselman <b...@xs4all.nl> wrote: > > Jonathan Greenberg wrote: >> >> The problem is that I'm trying to create a path to use with a system() >> call, and the command window will not work with the forward slash, >> only with the standard backslash.
