[R] Altering Forest plot in Metafor package

[Fosulli]

Dear All,

I'm having trouble tweaking a forest plot made using the R meta-analysis
package metafor. My main problem is that I have two studies which have very
large Confidence intervals and as such my forest plot is very wide, and not
neat. As I would like to add more descriptive columns into the plot too, I
was wondering if there was a way to cut the confidence interval in the graph
and add arrows to suggest that it continues on, while keeping the OR values
correct so that the reader can view the CI clearly.

what I am asking, but here is an example of what I am hoping is possible in
Metafor <http://r.789695.n4.nabble.com/file/n4709857/arrows.png>

Use the 'alim' argument (or the 'at' argument) to restrict the axis limits, so that CI bounds below/above are indicated with an arrow. And play around with the 'xlim' argument to make better use of the space in the plotting region. And the 'ilab' argument allows you to add columns with additional information to the plot. Please read help(forest.rma) carefully and especially try out all of the examples. They illustrate the use of these arguments.

Best,
Wolfgang
