[R-meta] Displaying Subgroups in Forest Plot

I am using the ‘forest’ function to plot the results from a ‘rma.mv’ model. I would like to stratify the forest plot into subgroups at the two levels of ‘VAR_X’. I do not understand how to tell the program what the variable is to stratify by. I see a lot of code such as “c(1:4)” and don’t really grasp what that is doing.

I have a total of 37 effects, where n=14 are in category 1 of ‘VAR_X’ and n=23 are in category 2 of ‘VAR_X’

Ideally I would like to present these with their pooled estimate at the bottom of each subgroup level chunk.

Thanks in advance!
