Fractional Factorial Design
Hi all,
Does anybody know if it is possible to build a fractional factorial design
in R? That is, suppose that we want do design an experiment with 3 factors
with 2, 3 and 3 levels, respectivly. However we want to consider, let's say,
only 6 from all possible level combinations. Does R design such experiment?
Thanks in advance,
Caio

Hi all,
I have managed to get the r-scale usage algorithm to work, but I need to obtain the final results from this. As I understand it, this code is designed to generate a matrix after processing and store it somewhere?????
Here is the code.....
I get this part of the code, it all makes sense.
##
if(nchar(Sys.getenv("LONG_TEST")) != 0) {R=1000} else {R=5}

Is there a good package for multiple imputation of missing values in R?
I'm looking for a package that has a start-of-the-art method of
imputation of missing values in a data frame with both continuous and
factor columns.
I've found transcan() in 'Hmisc', which appears to be possibly suited
to my needs, but I haven't been able to figure out how to get a new
data frame with the imputed values replaced (I don't have Herrell's book).
Any
