RELEASE NOTES 

		spatstat 1.14-10

		30 January 2009
	
	We thank Salma Anwar and Ang Qi Wei for contributions.

OVERVIEW
	New functions for generating random points on lines.
	New documentation about shapefiles.
	Minor improvements and bug fixes.

NEW DOCUMENTATION

	The package now includes a vignette (doc/shapefiles.pdf)
	explaining how to convert shapefiles into spatstat format.

NEW FUNCTIONS

	pointsOnLines
	runifpointOnLines
	rpoisppOnLines
		Given a line segment pattern, these functions generate
		(systematic or random) patterns of points 
		that lie on the line segments.

	quadrat.test.splitppp
		New method for quadrat.test for objects of class 'splitppp'.

IMPROVEMENTS/ENHANCEMENTS

	quadratcount
		The function 'quadratcount' is now generic,
		with methods for 'ppp' and 'splitppp'.

	pixellate
		new argument W determines the pixel grid.

	data(humberside)
		The pentagonal boundary of `humberside.convex' 
		has been modified very slightly 
		so that it encloses all the data points.

	data(humberside), data(urkiola)
		The internal format of these datasets was slightly incorrect
		(as described in bug [2]) and has now been repaired.
	
	internal code
		Several internal improvements in R code.
		Various minor glitches in the C and C++ code,
		detected by various compilers, have been repaired.
		Numerous help files have been corrected.

BUGS

	[1] predict.ppm, plot.ppm, plot.fii

		For a multitype point process model,
		these functions sometimes crashed 
		if the levels of the marks were not in alphabetical order.
		(Detected by Salma Anwar)
		Fixed.

	[2] owin, intersect.owin, intersect.tess, 
  	    quadrats, quadrat.test, quadratcount

		If 'df' was a data frame, then owin(poly=df)
		created an object with a slightly incorrect internal format. 
		This subsequently caused other functions to crash.
		Fixed.

	[3] plot.ppp
		Main header on the plot was incorrect if the
		point pattern contained 'reject' points.
		Fixed.
