The Metafor-Package, a meta analysis package for R
The metafor package is a free and open-source add-on for conducting meta-analyses with the statistical software R. The package consists of a collection of functions that allow the user to calculate various effect size or outcome measures, fit fixed-, random-, and mixed-effects models to such data, carry out moderator and meta-regression analyses, and create various types of meta-analytical plots.
On this website, you can find news and updates concerning the package, a more detailed description of the current and planned package features, instructions for downloading and installing the package, information on how to obtain documentation and help when using the package, and an (incomplete) list of published articles that have used the metafor package (or its predecessor, the mima function) as part of their analyses.
