R help - Apr 2006 - rmeta: forest plot problem

Der useRs,

I'm working on meta analysis using rmeta package. Using code below I 
plot the forest 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 anyone can 
explain the best way to solve my problem, I should be very grateful.

One of the examples from Paul Murrell's book (on his web page at
http://www.stat.auckland.ac.nz/~paul/RGraphics/chapter1.html) shows how to 
do a picture like this with grid graphics. It's fairly easy to customize.

PS: I have written a more general version of this but haven't added it to 
rmeta yet, and I don't have it with me today
