[R-meta] Displaying Subgroups in Forest Plot

[Dylan Johnson]

Thanks all � I have been following that code Wolfgang and it is coming together.



One issue I am having is that I have repeating author names and dates along the column in the forest plot where r is automatically adding a serial number to the end:



Johnson, 2018.1

Johnson, 2018.2

Johnson, 2018.3



Is there any way to remove that?

Dear Dylan,

There is a pretty coprehensive example here:

http://www.metafor-project.org/doku.php/plots:forest_plot_with_subgroups

This should be fairly easy to adapt to the case where rma.mv() is used for model fitting.

Best,
Wolfgang
