Many thanks for your reply! the Package ‘ggplot’ was removed from the CRAN repository. Formerly available versions can be obtained from the archive<http://cran.r-project.org/src/contrib/Archive/ggplot>(Unfortunately, I am a windows user). The metafor and meta.summaries() still need the (a,b,c,d) or standard errors for the effect estimates! I have the following data

rr <- c(0.61, 0.35, 1.16, 0.94, 1.16, 0.46, 0.99, 1.05, 1.15, 0.27) lci <- c(-1.69, -1.27, -0.24, -0.54, -1.01, -1.8,-0.89, -1.38, -1.05,-2.04) uci <- c(0.70, -0.82,0.54,0.41,1.30,0.24,0.87,1.48,1.33,-0.57) rrdata <- data.frame(rr,lci,uci)

I can compute standard errors from my data? but the results show different confidence interval?

Many thanks in advance,
Cheba
