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))

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.

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,
