Arguments specific to
biadbipl
Required argument. Two-way table in the form of a matrix
of size
p
×
q
representing observations on a response
variable depending on two factors.
X
Optional argument. Matrix of size
k
×
q
containing the
measurements of
k
new rows to be interpolated into the
biplot.
X.new.rows
Optional argument. Matrix of size
p
×
m
containing the
measurements of
m
new columns to be interpolated into
the biplot.
X.new.columns
Logical value requesting or suppressing adding of main
effects to calibrations on axes of an interaction biplot.
Defaults to FALSE.
add.maineffect
Logical value indicating whether main effects are shown on
the biplot axes of a biadditive biplot of the interaction
matrix. Defaults to FALSE.
show.maineffect
One of
"InteractionMat"
,
"Xmat"
,
"XminMeanMat"
specifying whether to use the interaction matrix (the
default), the two-way table itself or the two-way table
with the overall mean subtracted. As discussed in
Sections 6.1 - 6.5, biadditive biplots are mainly constructed
from the interaction matrix. The other two alternatives
above are rarely used but are available if needed.
biad.variant
1
/
2
Logical value indicating whether
V
or
V
is to be used
SigmaHalf
in plotting the rows.
NULL or an integer-valued vector specifying circles to be
drawn with diameter from a specified row point to the
origin. Intersections of the circle with the biplot axes
provide the predicted values for the specified row point.
circle.proj
NULL or scalar value for use together with
n.int
to ensure
at least two marker points appear on a biplot axis.
expand.markers
A single integer or character value specifying the colour of
all biplot axes. A vector of integers or character values
can be given to allow different colours for the different
biplot axes.
axis.col
Vector specifying colours of plotting symbols for the
columns. Defaults to
"red"
,i.e.
rep("red",
ncol(X))
.
column.points.col
Value specifying size of plotting symbol for the columns.
Defaults to 1.
column.points.size
Value specifying size of labels for the column points.
Defaults to 0.8.
column.points.
label.size
Logical value specifying whether labels of column points
are shown. Defaults to TRUE.
column.points.text
