metaplot and meta.summaries
...ocumentation for quite some time, I'd be very happy about some help with metaplot and meta.summaries. metaplot: --------- Can I change the label size? I've got 126 values and the intersection of the labels makes it impossible to read them. Why do I have to give sumse (Standard Error) and sumnn (Precision) of the summary estimate? I can calculate one from the other, right? Just to make sure I'm not misunderstanding something. metaplot(CoeffVector, StdErrorVector, nn=NULL, labels=Name, conf.level=0.95, xlab=paste(CoeffNames[j], CoefficientName[i]), ylab="Countries", xlim=N...

rmeta: forest plot problem
...st plot: library(rmeta) data (catheter) a<-meta.MH (n.trt, n.ctrl, col.trt, col.ctrl, data=catheter, names=Name, subset=c(13,6,5,3,7,12,4,11,1,8,10,2)) summary(a) # odds ratio values and confidence intervals metaplot(a$logOR, a$selogOR, nn=a$selogOR^-2,a$names, summn=a$logMH, sumse=a$selogMH, sumnn=a$selogMH^-2, logeffect=TRUE) Now I would like to add numerical odds ratio values and corresponding confidence intervals for each study on the second y axis (eg. http://www.statsdirect.com/help/meta_analysis/cochrane_plot.htm. I try with 'text' command, but the outcome is disastrous. If...

Meta-Analysis: Metaplot Labels, SE, and Summary
...pected 'a real' got 'Kovacs'. (Kovacs is the author of the first study listed in the matrix.) How can we label the plot with authors and dates if this method of inputting data does not work? Finally, we are unclear about the arguments "summn", "sumse", and "sumnn". To what should we set these arguments in order to create a summary line that illustrates the confidence interval of the mean of all effect sizes in our meta-analysis? Thank you very much. I apologize for my proven inability to resolve these issues without assistance. Best, Ishwar Bridgela...
