Given a colour map defined on a range of numerical values or a set of
 discrete inputs, the command restricts the range of values to a narrower range,
 or restricts the set of inputs to a subset, and returns the associated
 colour map.

restrict.colourmap

Defines spatial data types and supports geometrical operations
on them. Data types include point patterns, windows (domains),
pixel images, line segment patterns, tessellations and hyperframes.
Capabilities include creation and manipulation of data
(using command line or graphical interaction),
plotting, geometrical operations (rotation, shift, rescale,
affine transformation), convex hull, discretisation and
pixellation, Dirichlet tessellation, Delaunay triangulation,
pairwise distances, nearest-neighbour distances,
distance transform, morphological operations
(erosion, dilation, closing, opening), quadrat counting,
geometrical measurement, geometrical covariance,
colour maps, calculus on spatial domains,
Gaussian blur, level sets of images, transects of images,
intersections between objects, minimum distance matching.
(Excludes spatial data on a network, which are supported by
the package 'spatstat.linnet'.)
