RELEASE NOTES 

		spatstat 1.13-2

		14 May 2008
	
OVERVIEW
	Additional capabilities for summary functions.
	Simulation envelopes are now available in 'alltypes'.

NEW FUNCTIONS

	Ldot, Lcross
		L functions for multitype point patterns
		
	rjitter
		Applies an independent random displacement
		to each point in a point pattern

	with.fv
		Evaluates an expression inside a function value table.
		Examples:
		     with(Kest(redwood), sqrt(./pi))
		     with(Kest(redwood), max(abs(iso - theo)))

	eval.fasp
		Evaluate an expression involving function arrays.

	compatible.fasp
		Tests whether two function arrays are compatible.


IMPROVEMENTS/ENHANCEMENTS

	alltypes
		Now allows calculation of envelopes of 
		multitype summary functions, e.g.
			alltypes(betacells, "K", envelope=TRUE)

	[.fasp
		The subset operator for the class "fasp"
		now uses the argument 'drop'. This makes it easy
		to extract one of the functions in a function array.

	Gcross, Kcross, Jcross
		Computation has been slightly accelerated
		and the default y-axis labels have been improved.

	eval.fv
		Has a new argument 'envir' determining the environment
		in which the expression is evaluated.

	envelope
		Modified argument list


BUGS

	[1] Kcross, Kdot
		These functions ignored the 'correction' argument.
		Fixed.

	[2] as.fv
		Did not work correctly on a function array (class 'fasp').
		Fixed.
