32_multi-litmus_objects: Multi-Litmus Objects

In barsurf: Contour Plots, 3D Plots, Vector Fields and Heatmaps

Description

Color functions that combine multiple litmus objects.

Usage

mlitmus (..., default.color="#D0D0D0", na.color=default.color)

Arguments

...	One or more litmus objects.
default.color	String, color that is returned for values outside the litmus objects' knots.
na.color	String, color that is returned for NA values.

Details

This function creates a color function similar to a litmus object, containing one or more litmus objects.
(Noting that these functions return mlitmus objects, so you call these functions, and then if necessary you can evaluate the resulting function).

The color function works out which litmus object to use for each input value.

An example is using one set of colors for positive values and another set of colors for negative values.

Note that it's possible for litmus objects to overlap.
This may be changed, so this feature should not be used inside packages.

Value

An mlitmus object.
