aggregate vs tapply; is there a middle ground?
...INCLUDING results for
empty subsets, and still obtain a 2D array, matrix, or data.frame? OR
alternatively is there a simple way to mush the 4D result from the
tapply into a 2D matrix/data.frame?
thanks very much in advance for any help!

probability histogram question
...the value :
#[1] 10
I would really like to plot values in the probablility histogram that
sum to 1, not 10. Is there a switch in the hist(x) command that I'm
missing? Or, is there another function that can do this?
Thanks in advance,
jlb

Ordering boxplot factors
...the factors are ordered left-to-right along the x-axis by
median, not alphabetically by factor name.
Complicated ways abound, but I'm hoping for a magical one-liner that'll
do the trick.
Any suggestions would be treasured.
Thanks,

changing degrees of freedom in summary.lm()
...I have but 219-17=202 df. I'm probably being dense on this one,
but is there a way I can set df to the proper number so that summary.lm
does the correct significance test? Or should I be doing an entirely
different anlaysis?
Thanks,

SUMMARY: aggregate vs. tapply
...st(tmp, A ~ B, sum)
add.all.combinations(a, row="A", cols = "B")
Good thing there are so many code cats around, 'cause we have so darn
many ways to skin 'em. Thanks again to all who took the time to answer!!
