[R-meta] Forest plot with groups

[Sally Olderbak]

Hi Everyone,

We are trying to create a forest plot figure that graphs study-level 
estimates according to different variable categories. For example, I 
want to model effects for psychopathy and I want to group estimates by 
different factors within psychopathy. So the figure would include 
study-level estimates for Psychopathy Factor 1 followed by study-level 
estimates for Psychopathy Factor 2. Below each group, we would present 
the average effect size within that group, followed by a third estimate 
averaging across both groups. Here is an example of what we would like 
to do, but it is for the metafor package, which we cannot use because we 
have observations nested within studies.

Is this possible to do in Robumeta and if so, does anyone have any 
syntax they can share with us on how to do this?

Thank you in advance for your help!

best regards, Sally
