Actually, Scott suggested ggplot2, which is available on CRAN: http://cran.r-project.org/web/packages/ggplot2/index.html
Moreover, for the metafor package, you do not need "(a,b,c,d) or standard errors for the effect estimates". 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) The lci and uci values are obviously the log-transformed values of the upper and lower CI bounds for the RR. So, you could do: library(metafor) forest(log(rr), ci.lb=lci, ci.ub=uci, xlab="Log Relative Risk") or: forest(log(rr), ci.lb=lci, ci.ub=uci, xlab="Relative Risk", atransf=exp) help(forest.default) will tell you more about using the forest() function.

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?
