R help - Nov 2011 - 2^k experiment generator

Hello,

While looking for info on 2^k experimental design and anova I remember I saw
somewhere there was a function to generate all the experiments.  I can't
find the function anymore can anyone suggest?

The function takes as input the factors and levels and generates all the
experiments. I know I can do it myself using recursion but I want to avoid 1)
reinventing the wheel and 2) making mistakes while at it.

TIA,
Best regards,
Giovanni

Check out the Task View on Experimental Design:

http://cran.at.r-project.org/web/views/ExperimentalDesign.html

but perhaps packages rsm or qualityTools have what you want.

Never mind, found it, it is the expand.grid function.
