[R-meta] ODP: Create labels for funnel plot points in metafor

[Viechtbauer, Wolfgang (NP)]

Dear Barbara,

Use the 'slab' argument when either using escalc() or when fitting the model (e.g., with rma()) to set the study labels to whatever variable you like. See the documentation for examples:

Best,
Wolfgang
