plot.lda {MASS} | R Documentation |
Plots a set of data on one, two or more linear discriminants.
## S3 method for class 'lda'
plot(x, panel = panel.lda, ..., cex = 0.7, dimen,
abbrev = FALSE, xlab = "LD1", ylab = "LD2")
x |
An object of class |
panel |
the panel function used to plot the data. |
... |
additional arguments to |
cex |
graphics parameter |
dimen |
The number of linear discriminants to be used for the plot; if this
exceeds the number determined by |
abbrev |
whether the group labels are abbreviated on the plots. If |
xlab |
label for the x axis |
ylab |
label for the y axis |
This function is a method for the generic function
plot()
for class "lda"
.
It can be invoked by calling plot(x)
for an
object x
of the appropriate class, or directly by
calling plot.lda(x)
regardless of the
class of the object.
The behaviour is determined by the value of dimen
. For
dimen > 2
, a pairs
plot is used. For dimen = 2
, an
equiscaled scatter plot is drawn. For dimen = 1
, a set of
histograms or density plots are drawn. Use argument type
to
match "histogram"
or "density"
or "both"
.
