How to create a forest plot in r?

forest in metafor

The metafor package has the method forest. Most of the relevant help is under forest.default.

Here is one example

forest(r, sei=r_se, slab=study_name, xlab='r',
       at=seq(-.25, .75, .25))

• r is a vector of correlations
• r_se is the standard error for each correlations
• slab is an optional argument used to place the study names
• xlab is specified to make the graph easier to interpret
• at allows specification of the axis tick marks; defaults seemed to result in strange numbers. Overriding requires attention to the range of the data.
