...European women from the original database and conducted the following: women_west<-read.csv("women_west.csv") print(women_west) dat<-escalc(measure="ZCOR",ri=Pearson,ni=N,data=women_west,append=TRUE) res<-rma(yi,vi,data=dat) is.factor(dat$year) forest(res,transf=transf.ztor) In meta-regression, I used the original database, but used categorical moderators for sex (=women), and ethnicity (=european) to find the effect specifically in European women. adult<-read.csv("adult.csv") print(adult) dat<-escalc(measure="ZCOR",ri=Pearson,ni=N,data=adul...

...em is: How do I get the calculated results back into the form of raw correlation coefficients? (In order to report them in an article.) I see two cases, where this might be relevant: A) When reporting numeric results: I tried the following: print.rma.uni(MAergebnis, transf="transf.ztor") but then noticed that the following will bring up the same result: print.rma.uni(MAergebnis) (When using the "z2r" and "r2z" functions out of the "psychometric"-package on the separate numbers, the values change, so it can't simply be a matter of roun...

...39;m having trouble tweaking a forest 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. http://...
