    o Faster algorithms for simulating cluster processes.
    
    o Bug fixes and internal improvements.

NEW FUNCTIONS

    process using either the naive, Brix-Kendall, or Baddeley-Chang algorithm.
    
SIGNIFICANT USER-VISIBLE CHANGES

    o rCauchy, rThomas, rMatClust, rVarGamma
    These algorithms have been accelerated by several orders of magnitude
    in the case where the cluster radius is large.
    
    o rCauchy, rThomas, rMatClust, rVarGamma
    These functions now offer a choice of simulation algorithms.
    
    o rCauchy, rThomas, rMatClust, rVarGamma, rNeymanScott
    Formal arguments have changed. 

    o rNeymanScott
    Argument 'lmax' has been replaced by 'kappamax'.
    New argument 'mumax'.

    o rPoissonCluster
    Argument 'lmax' has been replaced by 'kappamax'.

BUG FIXES

    o rThomas, rMatClust, rCauchy, rVarGamma
    If the model was very close to a Poisson process,
    and if saveLambda=TRUE was selected,
    the attribute "Lambda" was incorrectly labelled "lambda".
    Fixed.

    o clusterradius
    Crashed sometimes with message about infinite values of the integrand.
    Fixed.

        CHANGES IN spatstat.random VERSION 3.1-0

NEW FUNCTIONS

    o dpakes, ppakes, qpakes, rpakes

    for the Pakes distribution.

    o Tweaks to placate package checker.


        CHANGES IN spatstat.random VERSION 3.0-0

OVERVIEW

    o We thank Liu Yijia for contributions.

    o spatstat.random now suggests the new packages 'spatstat.explore'
    and 'spatstat.model' rather than the old 'spatstat.core'.
    
    o Bug fixes and internal improvements.

SIGNIFICANT USER-VISIBLE CHANGES

    o Package dependence
    'spatstat.random' now suggests the new packages 'spatstat.explore'
    and 'spatstat.model' rather than the old 'spatstat.core'.
    
    o random generators
    Random generators now accept 'nsim=0', and return a zero-length list.
    
    o random generators
    Code in the case 'nsim > 1' has been accelerated.
    
BUG FIXES

    o rmpoint
    Crashed if 'f' was a pixel image.
    [Spotted by Liu Yijia.]
    Fixed.

        CHANGES IN spatstat.random VERSION 2.2-0

OVERVIEW

    o Bug fixes and internal improvements.

BUG FIXES

        CHANGES IN spatstat.random VERSION 2.1-0

OVERVIEW

    o Indefinite integral.

    o Internal repairs, code acceleration, and improvements.

        CHANGES IN spatstat.random VERSION 2.0-0

OVERVIEW

    o We thank Dominic Schuhmacher for contributions.

    o This is a new package containing code removed from spatstat.core

    o Bug fixes in rmh visual debugger.

    o Minor improvements

SIGNIFICANT USER-VISIBLE CHANGES

    o spatstat.random
    The 'spatstat.core' package has been divided into two packages,
    called 'spatstat.random' and 'spatstat.core'.
    The new 'spatstat.random' package consists of functions for
    generating random point patterns, and other random spatial data,
    that were originally in 'spatstat.core'.

    o rMatClust, rThomas, rCauchy, rVarGamma
    New argument 'nonempty'

BUG FIXES

    o rmh
    The visual debugger did not display accepted births and deaths correctly.
    [Spotted by Dominic Schuhmacher.]
    Fixed.

    o rmh
    The visual debugger exited prematurely sometimes,
    if the current state was the empty point pattern.
    [Spotted by Dominic Schuhmacher.]
    Fixed.
