Subgroup plot with metaprop "Error in x$labels[[i]] : subscript out of bounds"

[fohofmann]

Hi everyone.

I am trying to calculate proportional meta.analysis with clusters and subgroups. The meta-analysis works fine and as expected, however, forest() seems - at least for me - broken:

forest(res, subgroup=T)
Error in x$labels[[i]] : subscript out of bounds

A reproducible example:

# libraries
library(meta)
library(data.table)

# data
dt = data.table(
 ID = rep(1:5, each=3),
 AE = rep(c("minor","major","deadly"),5),
 ni = rep(c(25,19,101,32,50), each=3),
 xi = c(2,3,3,4,1,0,29,13,4,7,4,1,7,2,1) )

# meta-analysis & forest plot
res = metaprop(xi, ni, cluster=ID, subgroup=AE, data=dt, tau.common=T)
forest(res)

A similar issue was described earlier for metamean() ( #41 ), but was solved meanwhile.

Any help would be highly appreciated.
Best, Felix

Thank you for pointing out this bug (not directly related to issue #41). Should be fixed now.
