Hi Hadley,
That solved a lot of problems. Thanks!
Do you get a vertically oriented bar? Here I get 15 bars with a space
where the north bar, the 16th bar, should be.

I thought of your email when I ran across this link:

I think that you would have word your question more carefully for a longer
response.
Also, I use StatEt almost everyday. It works great with R. I have not u

A colleague is interested in modifying the ylim definition for individual
panels of a common bwplot plotting statement.
Is there an approach to modifying the bwplot function to allow for a
dynamic ylim range given different panel factors ?
He is using R 2.6.2 on a Linux distribution running from
Also, can I control for number of decimal places printed. Like when I use

Hi Peng,
Here is a suggestion using tapply:
R> with(x, tapply(Value, list(State, Month), FUN = sum))
R> with(x, tapply(Value, list(State, Year), FUN = sum))
R> with(x, tapply(Value, list(State, Year, Month), FUN = sum))
with 'x' your data set. Please take a look at ?tapply for more information.
try this:
> x
State Month Year Value
1 NC Jan 1996 1
2 NC Jan 1996 2
3 NC Feb 1997 2
4 NC Feb 1997 3
5 NC Mar 1998 3

Hello,
I have problem running WinBUGS from R.
The following example works in WinBUGS but it does not work in R through

Works for me. What is the error message you get?

Does anyone know what the problem is?

If you only want to count cells that are exactly 0.0 (not slightly different
due to rounding errors) then try:
> sum( x==0 )
If you want a little wiggle room for rounding error, then you can try something
like:
> sum( -0.001 < x & x < 0.001 )
Adjusting the number of 0's as you see fit
