The figure that you linked to was produced with the "metafor" package. It can also be used to produce a forest plot if you have means and corresponding standard errors of the means. The standard error of a mean is equal to SD / sqrt(n), so as long as you also know the sample sizes (n), you can convert those standard deviations to the standard errors.

Dev"). Can anyone suggest some function() {Package} which can take such file as an input and give following forest plot: http://bm2.genes.nig.ac.jp/RGM2/R_current/library/metafor/man/images/big_plot.rma.uni_001.png Thanks, Xin [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
