Create a color/char palette or for groups of outliers
Conveniance Functions to generate meaningfull color palettes for factors representing different types of outliers.

)outfac |
a factor given by an OutlierClassifier
(e.g. |
family |
a function generating a color palette from a numer of colors requested. |
extreme |
The color/char for extrem but not definitivly outlying observations. |
outlier |
The color/char for detected outliers. |
unknown |
The color/char for observation with unclear classification. |
other |
The character codes for other outlier classes. |
ok |
The color/char for nonoutlying usual observations. |
use |
a numerical vector giving the indices of the bits of the output to be represented. The sequence of the bits determins how each bit is represented. |
codes |
The color influences to be used for each bit. |
... |
further codings for other factorlevels |
This functions are provided for coveniance to quickly generate a palette of reasonable colors or plotting chars for groups of outliers classified by OutlierClassifier1.
a character vector of colors or a numeric vector of plot chars.
