In-Depth Information
Only used when
dim.biplot = 2
and
ax.type =
"predictive"
. Numeric vector of size
p
specifying the
x-coordinate of the parallel transformation of each axis.
Defaults to zero for each axis.
orthog.transx
Only used when
dim.biplot = 2
and
ax.type =
"predictive"
. Numeric vector of size
p
specifying the
y-coordinate of the parallel transformation of each axis.
Defaults to zero for each axis.
orthog.transy
Integer-valued vector specifying components of
VALUE
to be
printed. Defaults to 1:10, and NULL suppresses printing of
all output. The output list has the following components: 1,

output
Four-component numeric vector for regulating the legend
margins. Defaults to
c(3,1,3,1)
.
parlegendmar
Four-component numeric vector for regulating the figure
margins. Defaults to
rep(3,4)
.
parplotmar
Vector of size equal to the number of groups specifying
plotting characters for group means. Defaults to 0:10.
pch.means
Numeric value regulating the size of the plotting character for
displaying group means. Defaults to 1.
pch.means.size
Defaults to
"1"
for open circles. If FALSE, new points are
indicated by
"N1"
,
"N2"
, and so on.
pch.new
Colour specification for new points. Defaults to
"black"
.
pch.new.cols
Label specifications for plotting character of new points.
Defaults to NULL.
pch.new.labels
Numeric value specifying size of plotting character for new
sample points. Defaults to 0.75.
pch.new.size
Vector specifying plotting symbols for individual samples.
Defaults to 0:10.
pch.samples
Size of plotting symbol for individual samples. Defaults to 1.
pch.samples.size
One of
"Orthog"
,
"Hor"
or
"Paral"
specifying titles of
axes to appear orthogonal to the side of the figure; always
horizontally or always parallel to the side of the figure.
Default is
"Orthog"
.
pos
Used together with arguments
offset.m
and
side.label
to
optimize placement of labels (markers) of calibrations on
biplot axes. A
p
-component integer-valued vector
controlling placement of markers on each biplot axis: 1

to the right of
specified coordinates. Defaults to 1 for each axis.
to left, 3
above and 4
Logical value specifying whether a matrix with the predicted
values accompanying a three-dimensional PCA biplot is to
be returned. Default is TRUE.
