transform R function
Dear all, Why the transform function does not accept two statistics
functions?
a = data.frame(matrix(rnorm(20),ncol=2))
transform(a,M.1=mean(X1),M.2=mean(X2)) # does not works
#while:
transform(a,M.1=mean(X1),M2=log(abs(X2))) #works
Best regards

Computation for specific 2^k factorial designs
Hi R users:
I want to know if there is any package that makes
the specific computation 2^k factorial designs as in:
George E. P. Box, J. Stuart Hunter and William G. Hunter.
Statistics for Experimenters. Second Edition. 2005.
John Wiley & Sons.
They advice about the misuse of the ANOVA table
in this kind of designs in page 188.
Thank you for your help.

optimal factorial designs
Hi All,
recently I used Design Expert for some Design Of Experiment work.
I was happy with the interface to select which effects I want to see in my experiment, and which not.
For example: I can select of course my main effects, but also if I want to see interaction A:B, B:C, A:B:C,but not A:C.
This was very interessting as you can end up with fewer runs, especially in cases of 10 factors with

unbalanced mixed effects models for fully factorial designs
Does anyone know of a way of dealing with unbalanced mixed effects
(fixed and random factors) for fully factorial designs.
An example of such data is given below;
The response variable is SQRTRECRUITS
SEASON is a random factor
DENSITY is a fixed factor
Thus DENSITY:SEASON is a fixed factor.
Therefore, whereas the effects of SEASON and DENSITY:SEASON should be
tested against the overall

Is the only way to get the mouse location by using javascript? Or does
rails do it for me?!? :)
Does anyone have a simple script that they use? I''m trying to put a div

factorial experiments and repeated measures
Dear All,
I'm new to the list and relatively new to R (but not so to S-Plus) and I?ve
been asked to help study some experimental data.
In a factorial experiment (5 factors at 2 levels) the response-variable was
measured at various times (0, 2, 5, 7, ..., 30 days after start). There's just
one run for each factor combination! I intend to use the nlme library of
Pinheiro and Bates in a
