RELEASE NOTES 

		spatstat 1.14-1

		29 July 2008 
	
OVERVIEW
	Various extensions and bug fixes.

DEPENDENCE
	spatstat now requires 'deldir' version 0.0-7 or later.

NEW FUNCTIONS
	
	delaunay
		Computes the Delaunay triangulation of a point pattern.

	pcfcross
		Computes a cross-type version of the pair correlation function
		for multitype point patterns.

IMPROVEMENTS/ENHANCEMENTS

	alltypes
		alltypes(X, fun="pcf") computes the cross-type pair correlation
		function between each pair of types.

	rNeymanScott
		Now handles marked point patterns (i.e. each cluster may be a 
		marked point pattern).

	lurking
		Behaviour has been improved (see bugs [2] and [3]).
		The default smoothing parameters have been improved 
		for the case cumulative=FALSE.

	ppm, update.ppm
		Handling of models with covariates has been improved.

	fitted.ppm
	residuals.ppm
	quad.ppm
	dummy.ppm
		These functions have a new argument 'drop=FALSE'

BUGS

	[1] blur
		The default case, blur(X), crashed with a strange message.
		Fixed.

	[2] lurking
		Sometimes crashed with a warning about NA's in covariates. 
		Fixed.

	[3] lurking
		If 'covariate' was an expression, this function
		sometimes crashed with an obscure message that the
		covariate values were not numeric.
		Fixed.

	[4] rmh.ppm, rmhmodel.ppm
		Crashed in some cases if the interaction was BadGey(). 
		Fixed.
