Dear all,

I have a very simple question.  Simple, that is, if you know the answer.

I wish to delete a file in a given directory after having first checked its
existence.  I issue the following commands


Thus creating the directory.


If indicator is greater than zero then the file exists.  Now I wish to
remove this file.  However, I would like to make the code compatible for
Linux/Windows and Macs.

In Linux I would issue the command

system('rm paste(path,'filename',sep='')')

and this works just fine.  It does not however work for windows, and I have
no idea whether it would work on a mac.

Is there a single command thay escapes me?

Best Wishes

Roger Gill
