ColorScheme-class {Rggobi} | R Documentation |
A color scheme is a collection of colors that can be used to provide a particular style or theme. A color scheme has colors for the background and the labels/annotations, and a pallette of color values that can be used to display different values within the scheme. There are different types of schemes for displaying different effects or styles. For example, there are continuous or divergent schemes.
Objects can be created by calls of the form new("ColorScheme", ...)
.
Typically, we retrieve schemes using getColorSchemes
.
colors
:Color-class
, currently RGBColor-class
.background
:"Color"
. This is
used as the background color for displays using this scheme. annotations
:"Color"
. This is
used to color labels, etc., i.e. decorations on plots.criticalvalue
:"integer"
description
:"character"
. A
string giving a human readable description of the characteristics
of this color scheme.type
:"integer"
. An integer and
name describing the particular type of the color scheme.
These are currently qualitative, sequential, divergin and
spectral.
The integer value is used internally. Generally, R users will only
refer to these by the name of the type.system
:"integer"
. A name and
integer value identifying how the colors are
represented. Currently, we are only using RGB. name
:"character"
. A name for
identifying the color scheme.No methods defined with class "ColorScheme" in the signature.
