Previously you were allowed to change directory in an example.  Now 
you're not.  This makes sense:  the user might not want to change the 
working directory.

To fix this, just save the old directory, and restore it at the end of 
your example.  For example,

   olddir <- setwd(tempdir())
   # Run the rest of the example code here
   setwd(olddir)
