Usage
## S3 method for class 'logitreg':
plot(x, group = "all", npred = 100,
conf.int = 0.9, conf.type = c("none", "polygon", "lines"),
xlab = expression(D[ij]), ylab = "Pr (A+ | d)",
rug = TRUE, ticksize = 0.02,
col = "red", ref.col = "lightgrey",
lwd = 2, conf.lwd = 1, conf.lty = "dashed",
shade = "lightgrey", ...)
Arguments
x
object to plot; an object of class "logitreg"
, usually
the result of a call to logitreg
. group
The group to plot the logit model for. Can be one of the
group labels or "Combined"
to draw the individual logit
models. Alternatively, and the default, is to use "all"
,
which divides the plotting region into the requ
npred
number of points at which the fitted curves are evaluated
for plotting purposes.
conf.int
numeric; the confidence interval required.
conf.type
character; how should the confidence interval be
drawn. Default is not to draw the confidence interval.
xlab, ylab
character; the x and y axis labels.
rug
logical; should rug plots be drawn?
ticksize
The size of the tick marks used in rug plots.
col
The colour in which to draw the line representing the
fitted values.
ref.col
The colour of the reference lines drawn at 0 and 1.
lwd
The line width in which to draw the line representing the
fitted values.
conf.lwd, conf.lty
Line width and line type for the confidence
interval. Only used if conf.type = "lines"
is specified.
shade
The colour for the fill and border of the confidence
interval if conf.type = "polygon"
is specified.
