Size of name of an axis if as.axes is TRUE.

ax.name.size

If set to TRUE axes are calibrated. Defaults to FALSE.

calibrate

Currently only dim.plot = 2 is implemented.

dim.plot

If set to TRUE lambda-scaling is applied. Defaults to
FALSE.

lambda

See PCAbipl. line.length

Size of markers on axes. marker.size

Colour of markers on axes.

marker.col

See PCAbipl. n.int

See PCAbipl. offset

See PCAbipl. pos

See PCAbipl. pos.m

If set to TRUE, samples are also drawn resulting in a joint
plot. Default is FALSE.

samples.plot

See PCAbipl. side.label

If set to TRUE, the points for the variables are plotted as
VJ instead of V J (the default; see Section 10.2.1 for
details)

VJ.plot

zoomval

Value
In addition to a covariance monoplot a list with the following two components is returned:
cov.X , the covariance matrix of X and cor.X , the correlation matrix of X .

10.5.2 Function MonoPlot.cor

This is a function for constructing the correlation monoplot defined in Section 10.2.2. It
shares the following arguments with MonoPlot.cov :

X ax.name.col lambda offset.m

as.axes ax.name.size n.int pos

axis.col dim.plot offset pos.m

Arguments specific to MonoPlot.cor

Defaults to TRUE, requesting arrows to be drawn from the
origin to each point representing a variable.

arrows

Number of calibrations on monoplot axes. calib.no

Defaults to TRUE, requesting a circle with unit radius to be
drawn.

circle

Defaults to TRUE, requesting plotting the variables as points. plot.vars.points

Defaults to TRUE, requesting printing as part of the axis label
the measure of how well each variable approximates
unit.cor.approx , described below.

print.ax.approx
