The original spatstat package has been split into
several sub-packages.
This package spatstat.geom is one of the sub-packages. It contains functions for
-
definitions of spatial objects (point patterns, windows, pixel images, line segment patterns, tessellations, 3D point patterns, general multidimensional space-time point patterns, linear networks)
-
interactive data entry and editing for spatial objects
-
printing and plotting spatial objects (including colour images, contour plots, perspective views, composite images)
-
conversion of types (pixellation, discretisation, interpolation, solution set, level set)
-
basic summary information about spatial objects
-
subsetting, splitting, superimposing spatial patterns
-
extracting information such as spatial coordinates
-
identifying duplicated elements
-
geometrical transformations such as rotating, rescaling, shifting, reflecting, applying affine transformations
-
geometrical operations such as intersection, union, complement, set difference, convex hull, point-in-set
-
geometrical mensuration (measuring areas, lengths, angles, diameter)
-
distance operations: nearest neighbour, nearest neighbour distance, pairwise distances, distance map, distance transform
-
geometrical constructions (tessellations, triangulation, discretisation, bounding box)
-
mathematical morphology (erosion, dilation, opening, closing, morphological distance transform)
-
pixel-by-pixel arithmetic
-
set covariance function, convolution of images
-
graphical information (layered objects, colour maps, symbol maps)
-
quadrat counting
The reorganisation of spatstat into a family of packages is described
on the GitHub repository
spatstat/spatstat.
