Dear R-community,
I'm currently trying to assemble a forest plot using the "forest" function
from package "metaphor".
Works well. Even the regular "main"-argument works for adding a title to the
graph.
However, I would like to add one top row which explains the nature of the
columns. Very much like the usual header in spreadsheet programs.
For example: "Study" "Sample" "Sample Size" "Estimated Effect Size"
"CI 95%".
I tried to add "axis(3)", but apparently the forest plot isn't that kind of
graphic.
Does anyone have any idea?
Cheerio
