plot.uvmeta: Forest Plots

Description

Function to create forest plots for objects of class "uvmeta".

Usage

# S3 method for uvmeta
plot(x, sort = "asc", ...)

Arguments

x

An object of class "uvmeta"

sort

By default, studies are ordered by ascending effect size (sort="asc"). For study ordering by descending effect size, choose sort="desc". For any other value, study ordering is ignored.

…

Additional arguments which are passed to forest.

Details

The forest plot shows the performance estimates of each validation with corresponding confidence intervals. A polygon is added to the bottom of the forest plot, showing the summary estimate based on the model. A 95% prediction interval is added by default for random-effects models, the dotted line indicates its (approximate) bounds
