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
path<-'c:example/R/'
Thus creating the directory.
indicator<-length(grep(filename,path))
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
