I am trying to import data from a personal geodatabse into R. This code
worked previously, but I recently upgraded to Windows 7 and R 3.0.1 and it
no longer works. The error message is "Cannot open data source". Any ideas
why I am getting this error? Code and session info below. Thanks for the
help.
