After coding several hundred papers, I have accumulated a list of effect sizes (Cohen's d) for various learning interventions. Most of these have been calculated from means and standard deviations (these are no problem) while others have been derived from the published F or t statistic.
My query is - how do I enter ALL effect sizes into R using the metafor package to conduct the meta-analysis (i.e. calculate q and i*i, overall effect etc). I have been shown how to include the means and SDs, but can see no way of including the F- and t-derived d's. IN most cases, the F and t statistics are published with degrees of freedom and N, but usually not with SD or SE.

Any advice greatly appreciated.
