Since there's continuing interest in this, I'm summarising below what I sent privately earlier to Harold Doran; I've not heard back yet nor has it yet been followed up on the list.

Basically, he sent me a file he'd downloaded: asp.pdf from the http://lib.stat.cmu.edu/R/CRAN/ website, and I downloaded the same file from the same website.

His file contained only 15146 butes, while mine had 100484 bytes, and the first 15146 bytes of mine were identical to his. My file opened perfectly in Acrobat Reader. His, of course, did not!

The conclusion is that, for some reason, when he downloads from that mirror the files are truncated (since he has observed the problem with several from that mirror, but not from other mirrors). I have had no problems with about 6 files from that same mirror.

Whether this is due to a system problem local to Harold, or to a problem along the line between his site and that mirror, is something it's difficult to make suggestions about investigating.

Best wishes to all,
Ted.
