## S3 method for class 'metabin': labbe(x, y, xlim, ylim, xlab=NULL, ylab=NULL, TE.fixed=x$TE.fixed, TE.random=x$TE.random, comb.fixed=x$comb.fixed, comb.random=x$comb.random, axes=TRUE, pch=21, text=NULL, cex=1, col="black", bg="lightgray", lwd=1, lwd.fixed=lwd, lwd.random=lwd, lty.fixed=2, lty.random=9, sm=x$sm, weight, studlab=FALSE, cex.studlab=0.8, ...) ## Default S3 method: labbe(x, y, xlim, ylim, xlab=NULL, ylab=NULL, TE.fixed, TE.random, comb.fixed=FALSE, comb.random=FALSE, axes=TRUE, pch=21, text=NULL, cex=1, col="black", bg="lightgray", lwd=1, lwd.fixed=lwd, lwd.random=lwd, lty.fixed=2, lty.random=9, sm=NULL, weight, studlab=FALSE, cex.studlab=0.8, ...)
x |
The x coordinates of points of the L'Abbe
plot. Alternatively, an object of class metabin . |
y |
The y coordinates of the L'Abbe plot, optional if x
is an appropriate structure. |
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. |
TE.fixed |
A numeric or vector specifying combined fixed effect estimate(s). |
TE.random |
A numeric or vector specifying combined random effects estimate(s). |
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. |
col |
A vector with colour of plotting symbols. |
bg |
A vector with background colour of plotting symbols (only
used if pch in 21:25 ). |
lwd |
The line width. |
lwd.fixed |
The line width for fixed effect estimate (if
comb.fixed is not NULL or FALSE ). |
lwd.random |
The line width for random effects estimate (if
comb.random is not NULL or FALSE ). |
lty.fixed |
Line type (pooled fixed effect estimate). |
lty.random |
Line type (pooled random effects estimate). |
sm |
A character string indicating underlying summary measure,
i.e., "RD" , "RR" , "OR" . |
weight |
Either a numeric vector specifying relative sizes of
plotting symbols or a character string indicating which type of
plotting symbols is to be used for individual treatment
estimates. One of missing (see Details), "same" ,
"fixed" , or "random" , can be abbreviated. Plot symbols
have the same size for all studies or represent study weights from
fixed effect or random effects model. |
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$event.e then). |
cex.studlab |
Size of study labels. |
... |
Graphical parameters as in par may also be
passed as arguments. |
A L'Abbe plot is drawn in the active graphics window.
If comb.fixed
is TRUE, the pooled estimate of the fixed effect
model is plotted as a line. If comb.random
is TRUE, the pooled
estimate of the random effects model is plotted as a line.
Information from object x
is utilised if argument weight
is missing. Weights from the fixed effect model are used
(weight="fixed"
) if parameter x$comb.fixed
is
TRUE
; weights from the random effects model are used
(weight="random"
) if parameter x$comb.random
is TRUE
and x$comb.fixed
is FALSE
.
