plotNorm2 {prada} | R Documentation |
Plots objects derived from function
fitNorm2
in false color represenation.
plotNorm2(fn, colrange=c("gray82", "blue"), center=TRUE, selection=FALSE, ellipse=FALSE, pch=20, cex=1, ...)
fn |
List. Object derived from function
fitNorm2 |
colrange |
Character vector with valid color identifiers (eg name or RGB values) from which a smooth color palette is derived. |
center |
Logical. Assign center of distribution. |
selection |
Logical. Mark all points beyond selection. |
ellipse |
Logical. Plot area and borders of selection as ellipse. |
pch |
see par |
cex |
see par |
... |
further arguments that are passed on to plot . |
Produces a scatterplot of paired data showing the densities of
the fitted bivariate distribution from function
fitNorm
in false color
representation. Additionally a selection of data points can be
highlighted either by marking outliers or by showing its area.
A list containing items p, cov, mu, S
(density values for
each data pair, resulting object from call to cov.rob, midpoint of
distribution, covariance matrix).
