Make it so. Outside R.

At the command line, use cd before you start R. This should feel natural.

In a GUI file browser, double clicking on a file type assigned to a program by 
default sets the containing directory to be current directory before kicking 
off the program, so double-clicking on an empty Project.RData file will do it. 
Or you can use RStudio Project.Rproj files the same way.
