[R-meta] Regplot problem

[Viechtbauer, Wolfgang (SP)]

A reproducible example would help, but the error message is pretty clear. In the list called 'results_list', there is no element called 'gray_matter'. Compare:

list(a=1, b=2)[['a']]
list(a=1, b=2)[['c']]

This is not a regplot() issue, but a problem with 'results_list' and/or the names of the list elements.

Best,
Wolfgang
