./geography/R-spatstat.random, Random Generation Functionality for the spatstat Family

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 3.3.2, Package name: R-spatstat.random-3.3.2, Maintainer: pkgsrc-users

Functionality for random generation of spatial data in the 'spatstat'
family of packages. Generates random spatial patterns of points
according to many simple rules (complete spatial randomness, Poisson,
binomial, random grid, systematic, cell), randomised alteration of
patterns (thinning, random shift, jittering), simulated realisations
of random point processes including simple sequential inhibition,
Matern inhibition models, Neyman-Scott cluster processes (using
direct, Brix-Kendall, or hybrid algorithms), log-Gaussian Cox
processes, product shot noise cluster processes and Gibbs point
processes (using Metropolis-Hastings birth-death-shift algorithm,
alternating Gibbs sampler, or coupling-from-the-past perfect
simulation). Also generates random spatial patterns of line segments,
random tessellations, and random images (random noise, random
mosaics). Excludes random generation on a linear network, which is
covered by the separate package 'spatstat.linnet'.

Log message:
(..geography/R-spatstat.random) Update 3.2.2 to 3.3.2

        CHANGES IN spatstat.random VERSION 3.3-2

OVERVIEW

    o Tweaks to documentation.

    o Minor improvements.

SIGNIFICANT USER-VISIBLE CHANGES

    o rSSI
    New argument 'verbose' specifies whether to
    print progress reports when nsim > 1.

        CHANGES IN spatstat.random VERSION 3.3-1

OVERVIEW

    o Internal changes to satisfy CRAN package checker.

        CHANGES IN spatstat.random VERSION 3.3-0

OVERVIEW

    o We thank Abdollah Jalilian for contributions.

    o Now depends on 'spatstat.univar'

    o Some functions have been removed.

    o Bug fix in Gaussian random field simulation.

PACKAGE DEPENDENCE

    o spatstat.random now depends on the new package 'spatstat.univar'

SIGNIFICANT USER-VISIBLE CHANGES

    o indefinteg
    This function has been moved to the new package 'spatstat.univar'.

BUG FIXES

    o rLGCP
    The underlying simulation of the random field was incorrect
    if the pixel raster dimensions were not equal (i.e. number of columns
    not equal to number of rows).
    [Spotted by Abdollah Jalilian.]
    Fixed.

        CHANGES IN spatstat.random VERSION 3.2-3

OVERVIEW

    o Slightly accelerated.

    o Minor bug fixes.

SIGNIFICANT USER-VISIBLE CHANGES

    o spatstat.random
    Some computations are slightly accelerated.

BUG FIXES

    o rLGCP
    In certain special cases, an error message about incompatible images
    was issued, and in the resulting point pattern object X,
    the driving intensity image attr(X,"Lambda") had incorrect dimensions
    or spatial coordinates.
    Fixed.
