is.im

Tests whether its argument is a pixel image
 (object of class <code>"im"</code>).

manip

spatial

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'.)
