[R] forest plot metafor

[Mario Petretta]

Dear all,



I use metafor package to generate a forest plot showing the weight of each study in the plot.



I use the code:

library(metafor)

data(dat.bcg)

res <- rma(ai=tpos, bi=tneg, ci=cpos, di=cneg, data=dat.bcg, measure="RR",

           slab=paste(author, year, sep=", "), method="REML")

forest(res, showweights=TRUE)



It is possible to order the columns, placing the weights after effect size and CI?



A further query: using escalc (or rma), it is possible to add the weight of each study (other than yi and vi) to the data (in the example: data.bcg)?



Thanks for your attention
