forest() in {metafor} :: edit labels
Hi Kim and Others,
Can anyone please help me on how can I edit default labels ( "Study 1",
"Study 2",...)

It would be a great help. Thanks in advance,

Visualizing binary response data?
Hi All,
I'm dealing with binary response data for the first time, and I'm confused
about what kind of graphics I could explore in order to pick relevant
predictors and their relation with response variable.
I have 8-10 continuous predictors and 4-5 categorical predictors. Can anyone
suggest what kind of graphics I can explore to see how predictors behave
w.r.t. response variable...

refline in forest() {metafor}
Hello all,
I am using forest.rma to plot a random effects model meta-analysis. I noticed
that refline sets a vertical line indicating the null hypothesis.
Is there a way to draw another vertical line, possibly dashed, centered on the
summary estimate?
Prof. Viechtbauer, if you happen to read this, I'd like to thank you for making
an excellent package. I have been using the metafor package

Dear All,
I'm having trouble tweaking a forest plot made using the R

Do you know of an existing function that allows the production of
sensitivity and specificity forest plots?

add a header to a forest plot (metafor)
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:

Annotate forest plot 'forest.rma()' for meta-analysis with metafor package
Dear R-experts,
The forest.rma() function from the metafor package creates nice forest
plots for presenting the results of a meta-analysis. These plots can be
annotated for e.g. giving names to the columns. E.g. as in the
documentation of the package:
data(dat.bcg)
### meta-analysis of the log relative risks using a random-effects model
res <- rma(ai=tpos, bi=tneg, ci=cpos, di=cneg,

I want to produce a similar "Forest Plot" as it is on the following link,

I am learning to use the metafor package to conduct meta-regression analyses for a systematic review on multidisciplinary care interventions in chronic kidney disease. For the forest plots, I can't figure out how to plot unadjusted and adjusted models on the same plot. From top to bottom, I would like to be able have the unadjusted plot, the multivariate adjusted plot, then each

package metafor: error when setting 'col' and 'at' for a forest plot
I am using metafor to create forest plots. This code gives me the expected

forest(forest$OR, ci.lb=forest$Low, ci.ub=forest$High, at=log(c(.05, .25,
1, 10)), slab=forest$SNP, atransf=exp)
As does this (setting colors):

z to r transformation within print.rma.uni and forest from the package metafor
Dear R community,
I'm using the ,metafor'-package by Wolfgang Viechtbauer (Version: 0.5-5) to

as the raw data.
(By the way: Really a nice piece of work, Wolfgang! Thanks heaps.)

Frequency tables.
Hi All,
I'm a SAS user but I'm very much interested in learning R.
I use ODS system in SAS to make nice frequency tables. Is it possible to

directly for publications? Thank you.

My forest plot is not fit to windows in R software
Dear Fahimeh
It would help if you also told us what package you are using as there
are several which perform forest plots. I assume it is meta.
Your plot is cropped on three side as far as I can see. What parameters
did you give to the call of the graphics device? What happens if you use
a different graphics format like pdf? Then we may be able to see where
the issue lies.
