In that case, you'll have to debug it.  Run traceback after the error.  
.readRDS(pfile) is called in several different places; you'll need to 
find out where it's happening, and why it's failing. The traceback() 
will tell you where; you can use debug() on that function to single step 
through until you get to this line, and see what pfile is set to.

BTW, please keep the discussion in R-help; someone else may have better 
contributions than me.
