forest is generic. It can be used to create forest plots.
forest(x, ...)"rma", a vector with the observed effect size or outcomes, or an object of class "cumul.rma". See Details. In the first case, object x is a fitted model object coming from the rma.uni, rma.mh, or rma.peto functions. The corresponding method is then forest.rma.
Alternatively, object x can be a vector with observed effect size or outcomes. The corresponding method is then forest.default.
Finally, object x could be an object coming from the cumul.rma.uni, cumul.rma.mh, or cumul.rma.peto functions. The corresponding method is then forest.cumul.rma.
