Please note that I want to use log-scale on the x-axis which makes the polygon function sad.

Dear All, As an attempt to highlight the overall pattern in a Forest plot, I would like to "highlight" the area around HR=1. I cannot find any simple tools for painting a grey ribbon between 0.9 and 1.1. Any suggestions?
Hi Patrik, This is a bit indirect, but it may do what you want. The example plot is from the metafor package (see forest.default): forest(dat$yi, dat$vi) library(plotrix) gradient.rect(0.9,-0.1,1.1,14, reds=c(1,0.5,1),greens=c(1,0.5,1), blues=c(1,0.5,1),gradient="x",border=NA) par(new=TRUE) forest(dat$yi, dat$vi) Jim
