Although it is not terribly different from loading an .rda file you

Hi Gabor and Martin,
Thanks very much for the information. (and Gabor for the Fold() routine

Regarding changes, I wonder if the behavior of plot() on POSIXct objects
changed also. According to Rnews Vol. 4/1, p. 31,

dp - seq(Sys.time(),len=10,by=day)
I think you are right. Plot does seem to have changed and maybe its due to
a change in plot or maybe due to a change in some routine it in turn calls.
