Hello,
I have many subsets of x. I want to get the standard deviation
for each subset with the same factor levels. For "FUN=mean" and
"FUN=median" I am using "ave()".
Can anybody tell me the match of "ave()" for using "FUN=SD"?
At the beginning I used aggregate(), also for mean and median. But

Hello,
I have a question. I creat a PDF file with four rows and
two cols.
Is it possible to:

-ro center an image in the whole width (example: rows 4)
Thank's a lot.

Hello,
I have got two matrices with different length. The matrices have 3
columuns. The first two are coordinates. The third is a measurement.
Now I want to get a subtraction between every single value of the
third column (between matrix1 and matrix2), but only if the two

Hello,
is it possible to fill an array with no using of the recycling rule?
My problem. I want to fill an array but my values have not always
the same length.
My aim. I want to fill the array only ONE TIME. All vacent places
should be written with NA.
Thank's a lot.

Hello,
I started a graphic device:

main title of the graphic device. But when I use "mtext()" I can
only write in the "figure region" of my four plots.

I will get two colums not three and only the last colum are my values
(MEAN[,3]). The first is only a rising number.
I also tried:

can anybody tell me a easy way to change the mode of an "aggregate list" to

I found a solution but I looks cruel.
