IMHO it's dependend on your data size and the functions you use.
I'm getting same behaviour (suse9) when i use mysqlWriteTable and
reshape with large datasets and a
upgrade from 512MB to 1GB works much more better - but now i dream from
2GB-4GB.

Dear R users,
However, how do I compute sum(values*probabilities)? The

Dear Professor Dalgaard
It is the NA pattern on the left hand side that matters. Does it help
to use
seishin[!is.na(seishin) seishin==]-NA
?
Yes! the above line worked perfectly.
But why? To me, !is.na(seishin) seishin== seems redundant.
If you could explain this, it would be greatly

I'm having a mental block as to how I can automatically assign filenames
