Dear all,
I am struggling to add a prediction interval to a forest plot that was
created with forest.meta(), package "meta".
I checked the source of forest.meta() and realized that it is heavily
relying on grid. I am lacking any experience with grid graphics. So, I
am having difficulties to find out where the random effects estimate is
actually plotted in order to add prediction intervals.
I appreciate this is not a direct answer to your question but the
equivalent function in metafor (available from CRAN) does this and it
might be easier to use that.
Any help is much appreciated!
