Examples

## Locate MTV-data file "FLEISS93.MTV" in sub-directory of package "meta"
##
filename <- system.file("extdata/Fleiss93.MTV", package = "meta")
##
fleiss93.cc <- read.mtv(filename)

## Same result as R Command example(Fleiss93):
##
metabin(event.e, n.e, event.c, n.c,
        data=fleiss93.cc, subset=type=="D",
        studlab=paste(studlab, year))

## Same result: example(Fleiss93cont)
##
metacont(n.e, mean.e, sd.e, n.c, mean.c, sd.c,
        data=fleiss93.cc, subset=type=="C",
        studlab=paste(studlab, year))
