RELEASE NOTES 

		spatstat 1.12-5

		07 January 2008

	We thank Dominic Schuhmacher for contributions.
 	
OVERVIEW
	Extension of Kolmogorov-Smirnov test.
	Minor improvements to graphics and window manipulations.
	Bug fixes for point-in-polygon and window geometry algorithms.

NEW FUNCTIONS

	kstest.ppp
		Performs a Kolmogorov-Smirnov goodness-of-fit test of
		Complete Spatial Randomness for a point pattern dataset.

IMPROVEMENTS/ENHANCEMENTS

	kstest
		A new generic function kstest has been introduced,
		with methods for "ppp" and "ppm" objects. It performs
		the Kolmogorov-Smirnov goodness-of-fit test of
		fitted Poisson point process models.

	ks.test.ppm -> kstest.ppm
		The function ks.test.ppm has been renamed kstest.ppm
		and has become a method for the generic function kstest.

	lurking
	diagnose.ppm
	plot.diagppm
		These functions now handle graphical arguments 
		controlling the plot (such as lwd, lty, main)

	expand.owin
	bounding.box
		These functions now preserve the `unitname'
		(name of the unit of length)

	intersect.owin
	union.owin
		These functions have been accelerated.
		They also check that the two windows have
		compatible `unitnames'.


BUGS

	[1] Point-in-polygon test
		On some systems, in rare cases, the following error message
		would appear:
		     Error in switch(w$type, rectangle = { :
                     internal error: some scores are not equal to 0 or 1

		The error actually occurred in the function inside.xypolygon
		which tests whether an (x,y) point lies inside a given polygon.
		The user's original command could have been [.ppp or 
		ppm(), quadscheme() or several other functions.

		The error was caused by a rounding-error effect in the 
		point-in-polygon test algorithm. This has been repaired.
		The problem can still occur in extremely unusual cases,
		but it now generates a warning rather than an error.

	[2] intersect.owin
		If P was a polygonal window and R was a rectangle, 
		the result of intersect.owin(P, R) where P was a polygonal
		window was internally inconsistent, leading to obscure errors
		in other functions. [Detected by Dominic Schuhmacher.]
		Fixed.

	[3] plot.quadratcount, plot.quadrattest
		The argument 'col' was handled incorrectly.
		Fixed.
