RELEASE NOTES 

		spatstat 1.11-5

		14 May 2007
	
	We thank Colin Beale for alerting us to some bugs.

OVERVIEW
	Four bug fixes in the handling of multitype point patterns.
	Minor performance improvements.

IMPROVEMENTS/ENHANCEMENTS

	distmap.psp
		This function is now executed in C code
		making it faster and much less memory-hungry.

BUGS

	[1] rmh, rmh.default
		For certain multitype point process models,
		the simulated pattern generated by rmh
		would have marks that were NA.
		Fixed.

	[2] predict.ppm
		For multitype point process models, predict.ppm would
		sometimes crash with a message 
			`No appropriate method for "marks<-" '
		Fixed.

	[3] plot.ppp
		Crashed if ALL marks in the point pattern were NA.
		Fixed.

	[4] unique.ppm, duplicated.ppm
		duplicated.ppm had a bug in the case where x$marks
		is a factor. As a result, duplicated.ppm and unique.ppm
		did not correctly detect duplicated points in a multitype
		point pattern (unless the mark levels were integers).
		Fixed.

	[5] demo(spatstat)
		A warning message was issued about 
		an unrecognised character in a character string.
		Fixed.
