x |
An object of class meta ). |
byvar |
An optional vector containing grouping information (must
be of same length as x$TE ). |
bylab |
A character string with a label for the grouping variable. |
sortvar |
An optional vector used to sort the individual studies
(must be of same length as x$TE ). |
studlab |
A logical indicating whether study labels should be printed in the graph. |
level |
The level used to calculate confidence intervals for individual studies. |
level.comb |
The level used to calculate confidence intervals for pooled estimates. |
comb.f |
A logical indicating whether the pooled fixed effect estimate should be plotted. |
comb.r |
A logical indicating whether the pooled random effects estimate should be plotted. |
text.f |
A character string used in the plot to label the pooled fixed effects estimate. |
text.r |
A character string used in the plot to label the pooled random effects estimate. |
lty.f |
Line type (pooled fixed effect estimate). |
lty.r |
Line type (pooled random effects estimate). |
xlab |
A label for the x axis. |
xlim |
The x limits (min,max) of the plot. |
ylim |
The y limits (min,max) of the plot. |
lwd |
The line width. |
cex |
A numerical value giving the amount by which plotting text and symbols should be scaled relative to the default. |
cex.comb |
A numerical value giving the amount by which plotting text and symbols for pooled fixed and random effects estimates should be scaled. |
cex.axis |
The magnification to be used for axis annotation
relative to the current setting of cex . |
cex.lab |
The magnification to be used for x and y labels
relative to the current setting of cex . |
log |
A character string which contains "x" if the x axis
is to be logarithmic (other values for log are not
reasonable). |
axes |
A logical indicating whether the x axis should be drawn on the plot. |
allstudies |
A logical indicating whether studies with inestimable treatment effects should be plotted. |
weight |
A character string indicating which type of plotting
symbols is to be used for individual treatment estimates. One of
"same" and "fixed" , i.e., plot symbols have
the same size for all studies or represent the weight of the
study in the fixed effect model. |
scale.diamond |
A numerical value giving the amount by which the diamond representing pooled treatment effects should be scaled relative to the default. |
scale.square |
A numerical value giving the amount by which the square representing treatment effects in individual studies should be scaled relative to the default. |
... |
Graphical parameters as in par may also be
passed as arguments. |
col.i |
The color for individual study results and confidence limits. |
A forest plot, also called confidence interval plot, is drawn in the
active graphics window. Sub-group analyses are conducted and displayed
in the plot if byvar
is not missing.
