Forest Plots

Description

The function forest is generic. It can be used to create forest plots.

Usage

forest(x, ...)

Arguments

`x`	either an object of class `"rma"`, a vector with the observed effect size or outcomes, or an object of class `"cumul.rma"`. See ‘Details’.
`...`	other arguments.

Details

Currently, methods exist for three types of situations.

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.
