[R] Design of experiments: construction and calculation

[Bart Joosen]

Hi All,

after searching a while on the R-project help archives, I found that I can 
construct factorial design with the conf.design package.

But now, how can I construct a design for 2 parameters at 3 levels and 1 
parameter at 2 levels?


And, maybe more important: how do I calculate the effects?

Thanks in advance

Bart
