Hello, I'm using the rmeta package to perform a meta analysis using
summary statistics rather than raw data, and would like to analyze
the effects in three different subgroups of my data. Furthermore, I'd
like to plot this on one forest plot, with corresponding summary
weighted averages of the effects displayed beneath each subgroup.
I am able to generate the subgroup analyses by simply performing 3
separate meta-analyses with the desired subset of data. However, I
can't manage to plot everything on the same forest plot.
Maybe I'm wrong but the 'forest'-function (package 'meta',
<http://cran.at.r-project.org/web/packages/meta/meta.pdf>) should be
able to do what you want. I guess you could be interested in the 'byvar'
argument.
