Arguments
x
An object of class "plsreg2"
.
what
What to plot. Options are "variables"
and "observations"
.
comps
An integer vector of length two to indicate
which components to plot.
where
Where to plot the observations. A character
vector of length two to indicate which components to use
when plotting observations. This parameter will take into
account the values in comps
. Possible options are:
c("t","u")
for using x-y components,
c("t","t")
, for using x components, and
c("u","u")
for using y components. Default
c("t","t")
.
cex
Character expansion for labels and points.
col.xlabels
Color for labels of X-block
variables.
col.ylabels
Color for labels of Y-block
variables.
yfont
Integer for specifying which font to use for
Y-block labels. See font
in graphical parameters
par
. pos
Position for the text (see graphical
paramaters par
). offset
When pos
is specified, this value
gives the offset of the labels.
col.xarrows
Color for the X-block arrows.
col.yarrows
Color for the Y-block arrows.
lwd
The line width of arrows.
length
Length of the edges of the arrow head (in
inches).
angle
Angle from the shaft of the arrow to the
edge of the arrow head.
col.points
Color for the points when
what="observations"
.
pch
Plotting character symbol to use (see
par
). pt.bg
Background (fill) color for the points given
by pch=21:25
.
show.names
Logical indicating whether to show
labels of points. Only used when
what="observations"
.
xpd
Logical for controlling clipping region of
names and labels.
xlab
A title for the x axis.
ylab
A title for the y axis.
main
Main title of the plot.
col.main
Color of main title.
cex.main
Character expansion of main title.
col.axis
Color of axis annotations (tick marks and
labels).
show.grid
Logical indicating whether to show grid
lines.
col.grid
Color of grid lines. Only used when
show.grid=TRUE
.
...
Further arguments are passed to labels or
points.
