R help - Oct 2004 - meta.summaries and se's of effect sizes

Hi All,

I would like to use meta.summaries from package rmeta to do a meta-analysis.
I have available effect sizes as r's (which could be easily transformed to
effect sizes in terms of d's).

My problem is that I'm not sure what the se's of these r's should be
...

The r-values are themselves computed from F-tests and t-tests for various
studies. 

Are there R-functions that do meta-anlysis on r-values instead of d-values?

regards, ingmar

I'm not sure even what r-values and d-values are in this context.

meta.summaries takes a number of independent estimates of the same 
quantity together with standard errors and combines them to get a single 
estimate. It doesn't care what the quantity is.
