A vector with background colour of plotting symbols (only
used if pch in 21:25).
lwd
The line width for confidence intervals (see
funnel.meta).
pch.adjust
The plotting symbol used for the adjusted effect estimate.
cex.adjust
The magnification to be used for the plotting
symbol of the adjusted effect estimate.
col.adjust
Colour of plotting symbol for adjusted effect estimate.
bg.adjust
Background colour of plotting symbol for adjusted effect estimate.
line
A logical indicating whether adjusted regression line should be plotted.
xmin.line
Minimal value for the adjusted regression line (on x-axis).
xmax.line
Maximum value for the adjusted regression line (on x-axis).
lty.line
Line type of the adjusted regression line.
col.line
Color of the adjusted regression line.
lwd.line
The line width of the adjusted regression line.
shrunken
A logical indicating whether shrunken treatment
estimates should be plotted.
pch.shrunken
The plotting symbol used for shrunken effect estimates.
cex.shrunken
The magnification to be used for the plotting
symbol of the shrunken effect estimates.
col.shrunken
Colour of plotting symbol for shrunken effect estimates.
bg.shrunken
Background colour of plotting symbol for shrunken effect estimates.
lty.connect
Line type for line connecting original and
shrunken treatment estimates.
lwd.connect
The line width of the connecting lines.
col.connect
Color of the connecting lines.
backtransf
A logical indicating whether results should be
back transformed in printouts and plots. If backtransf=TRUE
(default), results for sm="OR" are printed as odds ratios
rather than log odds ratio, for example.

Additional arguments for funnel.meta
function.
Details
A funnel plot is drawn in the active graphics window. In addition
this function adds the adjusted effect estimate as well as a
nonlinear regression line (also called adjusted regression line) if
argument line is TRUE. The adjusted regression line is
representing the dependence of the treatment effect estimate on the
standard error across studies. The adjusted regression line is only
plotted in addition to the adjusted treatment effect if argument
method.adjust="beta0" (default) has been used in the
limitmeta function.
If argument shrunken is TRUE the shrunken effect
estimates are also plotted. Lines are connecting original and
shrunken effect estimates.
Internally, R function funnel.meta is called to create
a funnel plot. For more information see help page of the
funnel.meta function.
