In-Depth Information
Arguments with a specific meaning in
cabipl
Required argument. A two-way contingency table in
the form of a matrix with
p
rows and
q
columns.
X
Optional argument specifying
t
new points to be
interpolated into the biplot. Must be in the form of
a matrix with
t
rows and
q
columns or, if
t
=
X.new
1, a
q
-component vector.
ca.variant
One of
"PearsonResA"
,
"PearsonResB"
,
"IndepDev"
,
"ConRatioA"
,
"ConRatioB"
,
"Chisq2A"
,
"Chisq2B"
,
"Corr"
,
"RowProfA"
,
"RowProfB"
,
"PCA"
. Defaults to
"PearsonResA"
.
axis.col
Digits or character values for specifying
col
parameter for printing biplot axes. Defaults to
"red"
. Vector input allows for different colours
for the various biplot axes.
col.points.col
Specifies
col
parameter controlling the colour of
character for printing column points. Default is
"red"
.
col.points.size
Specifies
cex
parameter controlling the size of
character for printing column points. Defaults
to 1.
col.points.label.size
Specifies
cex
parameter controlling the size of
printing the labels of column points. Defaults to
0.6.
col.points.text
Logical TRUE or FALSE for turning on or off
printing of the labels of column points.
ConRatioMinOne
Logical TRUE or FALSE for displaying contingency
ratio (FALSE, the default) or contingency ratio
minus one.
lambda
Logical TRUE or FALSE. If FALSE, lambda is taken
as 1. Lambda controls stretching or shrinking of
column and row distances. Default is FALSE.
logCRat
Logical TRUE or FALSE for specifying whether the
biplot axes of contingency ratio approximation CA
biplot must be calibrated on a log scale or not.
Default is FALSE.
marker.col
Specifies the
col
argument for controlling the colour
of markers on biplot axes.
pch.row.points
Plotting character for plotting of row points. Default
is 16.
pch.col.points
Plotting character for plotting of column points.
Default is 15.
PearsonRes.scaled.markers
Logical TRUE or FALSE. Default is FALSE,
suppressing multiplication by sqrt(sum of elements
of
X
).
