[R-meta] Forest plot with groups

[Sally Olderbak]

Dear Wolfgang,

Thank you for that link! I was not aware of that work.

However, since we have done all of the study analyses in Robumeta, I 
would prefer to stick with that package if possible.

But I assume this means we will be limited with how we can present 
forest plots, and cannot do grouping as I described below?

best, Sally
