summary() should take keywords for the statistics desired.

summary(dataset, method="mean,median");

or something like it.  I would also add an option to have column related
outputs,

var n NA mean sdv min q1 med q3 max
x1  ...
x2  ...
x3  ...

I know one can write this, but it would be nice to have this standard.  summary
is such a basic function that it should be all set in every version of R.
