R help - Oct 2011 - Meta-analysis of test statistics in "metafor" package?

Hi -

I am conducting a meta-analysis and I have a matrix of f-statistics, Ns and
dfs from a series of studies that tested for an interaction in a 2x2 anova. 
I'd like to test whether the 2x2 interaction is significant in the
aggregate.  

Similarly, I have a matrix of chi-square statistics that I'd like to
meta-analyze.

How can I input these test statistics into the "metafor" package and
conduct
these meta-analyses?  I see how to input raw data or standardizes effect
sizes (e.g., d) into "metafor", but not test statistics.

Best,

David

I believe the MAd package may have what you are looking for.  It can 
call metafor for you.
