RELEASE NOTES 

		spatstat 1.6-10

		22 July 2005

OVERVIEW

	Facilities for handling summary functions and pixel images
	have been improved.

NEW STUFF

	1. help(spatstat)
		New help file containing an overall summary
		of the package. 

	2. eval.im
		New function to evaluate expressions involving pixel images.
		For example if X and Y are images, then eval.im(X+Y)
		is the image obtained by adding corresponding pixel values
		in X and Y.

	3. eval.fv
		New function to evaluate expressions involving 
		summary functions like K(r). 

	4. compatible.im
		Determines whether two pixel images have compatible dimensions.

	5. compatible.fv
		Determines whether two fv objects are comparable.


IMPROVEMENTS/ENHANCEMENTS

	1. Kinhom, Kmulti, Kdot, Kcross, Kest.fft, 
           Gdot, Gcross, Gmulti, Jcross, Jdot, Jmulti, 
	   pcf.ppp, pcf.fv, markcorr
		 The y axis label on the default plot
		 is now more specific, e.g. for Kinhom
		 the y axis label is now Kinhom(r) instead of K(r).

	2. Jest, Jdot, Jcross, Jmulti
		Components of the return value have been reordered.
		This should have minimal effect, except that 
		it improves the appearance of plots.

	3. plot.fv
		Improved calculation of y axis limits.

	4. class "fv"
	  	 A minor (probably invisible) change to internal structure
		 of "fv" objects. The attribute "ylab" can now be 
		 an R language object.

COMPATIBILITY

	Jest, Jdot, Jcross, Jmulti
		plots will have slightly different appearance
		from before.

	eval.fv
		Although eval.fv is compatible with older versions of 
		spatstat, the y axis label in plot(eval.fv(....)) may
		look strange. You can simply override the default y axis
		label (with the argument ylab to plot.fv). Alternatively
		existing objects of class "fv" should be
		recomputed in spatstat 1.6-10. 
BUGS

	None found.
