Dear R developers---of course, I have my own function that does this,
but I think this would be useful for others, too. summary() already
returns the first moment, and I would hope most of us think of the
standard deviation as a pretty common summary statistic.
not to clutter this mailing list, but it would also be useful to have
an optional parameter that creates a different type of output,
stacking the univariate outputs, along the lines of
for (i in 1:ncol(d)) cat(names(d)[i], summary(d[i]), "\n")
of course, both of these suggestions may be useful but are not necessary.
my biggest suggestion is still to issue an "ambiguity warning" when
"<-[0-9]" is encountered, suggesting to users either to use '<-[
][0-9]' or '<[ ]-[0-9]' spacing for disambiguation. this would help a
lot of my students who are newcomers.
regards,
/iaw
