Great! Of course, more wants more, so.... 


oneway.test (or F.test)	(same as summary(aov(y~g)), but lower level of

and BTW:
What is the relation between chisq.test and the chisquare.test that
comes with R-0.15

- and while I'm in greedy-mode,

it would be nice to have

cdfplot (empirical cumulative distribution function)
survplot (Kaplan-Meier plot of survival fct.)

Splus has the former as (R has a stripplot there), but
for tutorial purposes, I'd like to see it as the familiar jagged curves shown in textbooks.
Same thing with K-M.

and (now I'm dreaming, not even Splus has this)

pairwise(...)	Multiple comparisons (HSD, Scheffe, Bonferroni)
