R help - Aug 2011 - Difference between a data frame and data table

I didn't learn about data tables until recently. (They're never covered
in
any intro R books).

In any case, I'm not sure what (if any) is the difference between a data
frame and a data table.

Can anyone provide a brief explanation?

Is one preferred over another or is it just dependent on the task at hand?


Thanks,
Abraham M.

Google on "R data table" please. Read the vignettes therein.

"Men by nature long to get on to the ultimate truths, and will often
be impatient with elementary studies or fight shy of them. If it were
possible to reach the ultimate truths without the elementary studies
usually prefixed to them, these would not be preparatory studies but
superfluous diversions."
