In R package *meta*, you can use
- metacont() for two groups providing means, SDs, and sample sizes,
- metamean() for a single group.
The standard effect size measures (Hedges' g, Cohen's, and Glass' delta)
are available in metacont().
You can use the R commands 'help(metacont)' and 'help(metamean)' to get
information on these functions.
Furthermore, the commands 'example(metacont)' and 'help(metamean)' will
run some analyses (and produce a forest plot for metacont).
Best wishes, Guido
