Dear Sir or Madam, I am trying to plot forest plot. I extracted odds ratio and their corresponding 95% confidence interval from papers, then I calculated the log(OR) and standard error using the following command OR<-metagen(logOR,selogOR,sm="OR") forest(OR,comb.fixed=TRUE,comb.random=TRUE,digits=2) However, it does not produce a forest plot. Can someone kindly help? Thank you in advance. Best wishes weiwei [[alternative HTML version deleted]]
The correct command for forest plot should be "plot" (instead of "forest") if you are using metagen from meta package.

You can also do meta.summaries() - from rmeta package - followed by a plot() on the resulting object. Or for a much more flexible plot try forestplot() function, also from rmeta package, but this requires a bit of work to set it up.
