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 to...

forest + igraph ?
Hello,
Is it possible to have two meta-plots in one graph (not par(mfrow=c(2,1))? But somthing like
library(metafor)
library("igraph")
if (interactive()) {
forest(dat.Treat$RR, ci.lb=dat.Treat$lower, ci.ub=dat.Treat$upper, xlab="Relative Risk",slab=dat.Treat$ID,refline=1)
forest(dat.Control$RR, ci.lb=dat.Control$lower, ci.ub=dat.Control$upper, xlab="Relative Risk",slab=dat.Control$ID,refline=1)
}
i.e. both metaplots on the same graph!
Regards,
Samor

Using Metafor package: how to backtransform model coefficients when Freeman Tukey double arcine transformation is used
Hello,
I am performing a meta-analysis using the metafor package. My data are
proportions and I used the Freeman Tukey double arcine (FT)
transformation to fit the random effects model. Now I want to create a
forest plot with my estimates backtransformed to the original scale of
proportions. Can this be done?

tweaking forest plot (metafor package)
...orest plot made using the R
meta-analysis package metafor. I did the analysis based upon the
correlation coeff from studies and plotted the corresponding forest
plot easily
> q2<-rma(yi,vi,mods=cbind(grupo),data=qim)
> q2
> forest (q2,transf=transf.ztor,digits=3, ... ,alim=c(0,1),refline=.5)
> text(-1.55,42,"Esp?cie [ref?]",pos=4,font=2)
I'd like to subdivide the "table" by the moderator 'grupo' - i.e.
create the necessary spacings in the list of studies to accommodate
the moderator statistics (cf.

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
plot (setting x axis tick marks):
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):
forest(forest$OR, ci.lb=forest$Low, ci.ub=forest$High, col=c(1,2,3),
slab=forest$SNP, atransf=exp)
But if I try to set both 'at' and
