Usage
"plot"(x, data, coords, group, colors, pch, mcolors, mpch, pcex, mcex, ...)
Arguments
x
an object of class "fda"
.
data
the data to plot in the discriminant coordinates. If
group="true"
, then data should be a data frame with the same variables that were used in the fit. If group="predicted"
,
data
need not contain the response variable, and can in fact
be the correctly-sized "x"
matrix.
coords
vector of coordinates to plot, with default
coords="c(1,2)"
. All pairs of plots are produced.
group
if group="true"
(the default), each point is color
and symbol coded according to the response in data
. If
group="predicted"
, the class of each point is predicted from
the model, and used instead.
colors
a vector of colors to be used in the plotting.
pch
a vector of plotting characters.
mcolors
a vector of colors for the class centroids; default is colors
.
mpch
a vector of plotting characters for the centroids.
pcex
character expansion factor for the points; defualt is pcex="0.5"
.
mcex
character expansion factor for the centroids; defualt is pcex="2.5"
.
...
further arguments to be passed to or from methods.
