RELEASE NOTES 

		spatstat 1.10-3

		20 November 2006

	We thank Mi Xiangcheng for spotting a bug.

OVERVIEW
	Faster computation of some summary statistics.
	Extended support for units of length.
	Bugs fixed.	

NEW FUNCTIONS
	
	rescale
		Changes the units of length
		in a point pattern or window	

	units.psp
	units<-.psp
		Units of length for line segment patterns

IMPROVEMENTS/ENHANCEMENTS
	
	Gcross
	Gdot
	Gmulti
		These functions have been accelerated by 
		a factor of 6 in large datasets.

	Jdot, Jcross, Jmulti
		These functions are also accelerated.
		Their argument lists have been modified slightly.

	markcorr
		Calculation accelerated.
		Improved default for argument f.

	nncross
		Now deals with the case where the two point patterns
		X and Y may have some points in common.

	units
	units<- 
		The unit of length may now include a `multiplier'
		e.g. 1 unit may equal 0.5 feet or 100 metres.

	distmap.ppp
	distmap.psp
	distmap.owin
	print.psp
	summary.psp
		These functions now support a unit of length.

	data(amacrine)
	data(bramblecanes)
	data(demopat)
	data(hamster)
	data(humberside)
	data(japanesepines)
	data(lansing)
		These point pattern datasets now have a unit of length.

BUGS

	[1] Gcross, Gdot, Gmulti
		(introduced in spatstat 1.9-2)
		If the points of different types were extremely far apart,
		the error message
			"incompatible types (from NULL to logical) 
			in subassignment type fix"
		sometimes occurred. 
		Fixed.

	[2] markcorr
		(introduced in spatstat 1.9-2)
		A constant in the denominator was calculated 
		incorrectly. Hence the estimate of the mark correlation
		function was incorrect by a constant factor (usually
		a small error).
		Fixed.
