Metaanalysis plot (forest plot)
Description
Plot confidence intervals with boxes indicating the sample
size/precision and optionally a diamond indicating a summary
confidence interval. This function is usually called by plot
methods for metaanalysis objects. Additional, you can specifiy your
own lower and upper boarder from the confidence interval.
Usage
1 2 3 4 5 6  metaplot.surv(mn, se=NULL, lower=NULL, upper=NULL, nn=NULL,
labels=NULL, conf.level = .95, xlab = "", ylab = "", xlim = NULL,
summn = NULL, sumse = NULL, sumlower = NULL, sumupper = NULL,
sumnn = NULL, summlabel = "Summary", logeffect = FALSE,
lwd = 2, boxsize = 1, zero = as.numeric(logeffect),
colors, xaxt="s", logticks=TRUE, ... )

Arguments
mn

precision: box ares is proportional to this. 
labels 
labels for each interval 
conf.level 
Confidence level for confidence intervals 
xlab 
label for the point estimate axis
