Hi ,
I am looking to making a panel of pie charts fo some of my dritribution data
. I was wondering if there is a way in any R package to write a small script to
do so.
Thanks,
Amin

There was a bug in 2.6.1 which has since been corrected: there is no need
to report corrected bugs in obsolete versions. Two different ways to
compute the sd of a zero-length vector gave different answers.
This is covered by the following NEWS item for 2.7.0 (version from
R-patched)

Hi Art,
Ignore the last email, I realized that I had already written the "add"
bit and it will be in plotrix 2.4-5. As far as I can see, both the
"type" and "xlim" problems are solved.

Hi rcoder,
Assuming that the number of rows of your matrix x is even, try also:
x <- matrix(1:72,12)
apply(x,2, tapply, rep(1:(nrow(x)/2),each=2),prod)
# or using a function which argument "x" is your matrix
prod.mat=function(x) {
k=nrow(x)
g=rep(1:(k/2),each=2)

I was attempted to install 2.7.1 in my mac only recently because of

I had no problem in building from source.
But after installation, I always got font warnings as following when

In the previous versions of R (2.6.1), when a vector of NA was given to the
functions 'sd' or 'var' with parameter na.rm = TRUE, it used to return NA. Now
(2.7.1) it returns an ERROR :
Example in 2.6.1:
> sd(c(NA, NA, NA, NA), na.rm = TRUE)
[1] NA
Example in 2.7.1:

Is this what you are after: this comes from the example of wilcox.test
and shows the structure and how to reference the p-value:

Hi R Gurus!
When you build a package, you need to put in keywords in the Rd files.
Where would you find the list of keywords, please?
