Hi Erin, If you want to use .First, just put it in the directory where you start up your R session, use it to change all the options that you want for all projects, then source a file to switch to the directory that you want. I call mine "SelectAnalysis.R" and it just displays a list of current projects from which I select one with a letter key.
