RELEASE NOTES 

		spatstat 1.5-4

	 	24 September 2004


OVERVIEW

	Minor enhancements have been made, and a few bugs fixed.
	Three new datasets have been added.


NEW STUFF

	New datasets:
		japanesepines	Japanese pines (Numata)
		finpines	Finnish pines (Kellomaki/Penttinen)
		spruces		Norwegian spruces in Saxonia (Fiksel/Stoyan)

IMPROVEMENTS/ENHANCEMENTS

	unmark() now handles objects produced by split.ppp()
	so that you can type
		plot(unmark(split(lansing)))

	The functions intersect.owin() and union.owin(),
	which were already present, are now documented!

	ppp() now checks that the arguments x and y
	are numeric, and strips off any names attached to them.

	Behaviour of example(applynbd) improved.

BUGS
	
	[1]. rmh() often used the incorrect default value for
	the argument 'start'. Fixed.

	[2]. plot.fv() did not handle 'xlim' correctly. Fixed.

	[3]. bug in example(im) fixed.
