Arguments
x
An object of class meta, or estimated treatment
effect in individual studies.
y
Standard error of estimated treatment effect.
xlim
The x limits (min,max) of the plot.
ylim
The y limits (min,max) of the plot.
xlab
A label for the x axis.
ylab
A label for the y axis.
comb.fixed
A logical indicating whether the pooled fixed effect
estimate should be plotted.
comb.random
A logical indicating whether the pooled random
effects estimate should be plotted.
axes
A logical indicating whether axes should be drawn on the
plot.
pch
The plotting symbol used for individual studies.
text
A character vector specifying the text to be used instead
of plotting symbol.
cex
The magnification to be used for plotting symbol.
lty.fixed
Line type (pooled fixed effect estimate).
lty.random
Line type (pooled random effects estimate).
col
A vector with colour of plotting symbols.
bg
A vector with background colour of plotting symbols (only
used if pch in 21:25).
col.fixed
Color of line representign fixed effect estimate.
col.random
Color of line representign random effects estimate.
lwd
The line width for confidence intervals (if level is
not NULL).
lwd.fixed
The line width for fixed effect estimate (if
comb.fixed is not NULL).
lwd.random
The line width for random effects estimate (if
comb.random is not NULL).
log
A character string which contains "x" if the x axis
is to be logarithmic, "y" if the y axis is to be logarithmic
and "xy" or "yx" if both axes are to be logarithmic
(applies only to function
yaxis
A character string indicating which type of weights are
to be used. Either "se", "invvar", "invse", or "size"
(applies only to function funnel).
sm
A character string indicating underlying summary measure,
e.g., "RD", "RR", "OR", "AS", "MD",
"SMD" (applies only to function funnel).
contour.levels
A numeric vector specifying contour levels to
produce contour-enhanced funnel plot.
col.contour
Colour of contours.
ref
Reference value (null effect) used to produce
contour-enhanced funnel plot.
level
The confidence level utilised in the plot. For the funnel
plot, confidence limits are not drawn if yaxis="size".
studlab
A logical indicating whether study labels should be
printed in the graph. A vector with study labels can also be
provided (must be of same length as x$TE then).
cex.studlab
Size of study labels.

Graphical arguments as in par may also be
passed as arguments.
