In this post, I’ll show how quick-and-dirty forest and funnel plots can be created with the metafor
package. After, I’ll show how we can instead use the ggplot2
package to create forest plots and use the ggplot2
package to create funnel plots, so that we can have pretty plots that are easy to change/stylize, and that can be produced regardless of which meta-analysis package for R
that you elect to use. Continue reading
