RELEASE NOTES 

		spatstat 1.20-1

		26 July 2010
	
OVERVIEW

    Further increases in speed and efficiency of ppm and rmh.
    New pairwise interaction model.


NEW FUNCTIONS


    DiggleGatesStibbard
	The Diggle-Gates-Stibbard model
	pairwise interaction for use in ppm()

IMPROVEMENTS/ENHANCEMENTS


    ppm
    	has been accelerated by a factor of 10 for the BadGey interaction.

    rmh
    	simulation of the Lennard-Jones model (cif='lennard')
	has been greatly accelerated.

    rmh, rmhmodel.ppm
    	Point process models fitted by ppm() using the DiggleGatesStibbard
	interaction can be simulated automatically using rmh.

BUGS

    [1] fitin
    	The plot of a fitted Hardcore interaction was incorrect.
	Fixed.
