RELEASE NOTES 

		spatstat 1.6-9

		1 July 2005

OVERVIEW

	One new dataset added.
	Minor improvements and bug fixes.

NEW DATASET

	chorley
		The Chorley-South Ribble cancer data


IMPROVEMENTS/ENHANCEMENTS

	1. Kinhom
		The arguments of Kinhom() have been altered.
		The existing argument 'lambda' is no longer permitted
		to be a matrix. Instead there is a supplementary matrix 
		argument 'lambda2'.

		Help file for Kinhom also expanded and improved.

	2. Kest
		The `correction' argument is now interpreted using
		partial matching, for example
			Kest(X, correction="tr")
		is interpreted as 
			Kest(X, correction="translate")
		
	3. envelope
		This function now does more error detection,
		making it more robust.

COMPATIBILITY

	Kinhom:
		the 'lambda' argument is no longer permitted to be
		a matrix. 

BUGS

	[1] Kinhom produced INCORRECT values for the 'border'
	estimate when the argument 'lambda' was given as a matrix.
	Fixed.
	
	[2] Functions such as Kest, Gest, Jest, .....
	sometimes crashed when the argument 'r' was given,
	complaining (falsely) that the values of r were not equally spaced.
	Fixed.

	[3] 'envelope' crashed if the data point pattern
	was a marked point pattern with numerical marks.
	Fixed.

	[4] 'superimpose' sometimes crashed when
	arguments were given in 'name=value' form.
	Fixed.

	[5] 'Kest' had a tiny bug, affecting the range of the argument r
	shown in some plots. 
	Fixed.
