[R] problem with loadURL -- claims newer version used- fixed

Thanks.  That was the problem.  I was transferring the files from my 
Mac to my web server (also a Mac) using Interarchy.  It was putting 
in CRs rather than LFs (the Interarchy options were "old Mac cr" vs. 
Unix (lf)").  Changing that transfer option makes it work.

load(url(someURL))  works (once I fixed the transfer to the server), 
although I used the other form because I was following the help for 
load. Perhaps the ?load comments could be modified to suggest 
load(url(someURL)) instead of suggesting loadURL(someURL).

Thanks for the very rapid response.
