[R-meta] Superscript in Forest plot (meta)

[Guido Schwarzer]

Tobias,

Good to hear that you found a solution.

I somewhat extended your R code to make it more general.

library(meta)
data(Fleiss1993bin)

refs <- 20 + seq_len(nrow(Fleiss1993bin))
mylabs <- NA
##
for (i in seq_len(nrow(Fleiss1993bin)))
   mylabs[i] <-
     as.expression(substitute(study^ref~(year),
                              list(study = Fleiss1993bin$study[i],
                                   ref = refs[i],
                                   year = Fleiss1993bin$year[i])))
##
mylabs

m <- metabin(d.asp, n.asp, d.plac, n.plac, data = Fleiss1993bin,
              studlab = paste(study, year),
              sm = "OR", comb.random = FALSE)

pdf("forest-study-ref-year.pdf", width = 8.5, height = 3.5)
forest(m, studlab = mylabs)
dev.off()

Best wishes, Guido
