		spatstat 1.12-0

		20 August 2007
	
	We thank Janet Franklin, Roger Bivand and John Rudge for contributions.

OVERVIEW
	New class of `hyperframes'.
	Three new functions and a new dataset.

NEW DATASETS

	ponderosa
		Ponderosa pine tree dataset of Getis and Franklin (1987)
		kindly provided by Janet Franklin.

NEW FUNCTIONS
	
	Lest
		Estimate Ripley's L-function L(r) = sqrt(K(r)/pi)

	localL, localK
		Getis-Franklin neighbourhood density function

	smooth.ppp
		Spatial smoothing of marks
		(smoothing of observations at irregular points)

NEW CLASS

	hyperframe
		A hyperframe is like a data frame, except that the
		entries can be objects of any kind, such as 
		images, functions, point patterns, windows etc.

		Methods for the class of hyperframes are defined
		for the following functions:
		
			print
			plot
			summary
			print.summary
			[
			[<-
			$
			$<-
			as.data.frame
			as.list
			names
			names<-	
			row.names
			row.names<-

		The following functions are also defined:
			
			hyperframe		create a hyperframe
			is.hyperframe		test whether x is a hyperframe
			cbind.hyperframe	combine hyperframes
			eval.hyper		compute expression on each row


BUGS
