[R] Changing working directory

[Walter Paczkowski]

Good morning,

I keep copies my .RData file in different directories for different projects on Windows XP.  There is an icon on my desktop for each project so all I have to do is click on the icon to open R for a specific project, i.e. a specific .RData file.  How do I change to another .RData file from within R without first closing R?

Thanks,
