This is not a good idea! MIME attachments do not survive the trip
through JitterBug. So to read your data, one has to find a separate
base64 decoder and feed it the above gibberish. (And even if we could
get the remailer to handle it, it would still be a problem with the
filed text.)

It can't be that hard to cook up a smaller, plaintext example? E.g.

> f1<-data.frame(a=1:2,b=3:4)
> f2<-f1
> f2[3,]<-f1[2,]
Error: couldn't find function "xpdrows.data.frame"

..which, incidentally, is fixed in the 0.63.3 snapshots.
