Quantlet:		SPPPsetregion
Description:		Sets the rectangular spatial domain for spatial point pattern analysis.

Usage:	`SPPPsetregion (pp)`
Input:
	`pp`	list - consisting of area (and possibly other components) - either previously created by a call to SPPPinit or created from scratch

Note:

C-Code from Venables, Ripley (1999) forms the basis of this quantlet. Also check this reference for more details.

Example:

; load the spatial statistics library library ("spatial") ; read a spatial data set pines = read ("pines.dat") ; initialize a point process pinesobj = SPPPinit (pines, 0, 96, 0, 100, 10) ; explicitly set region (although this is already ; done in SPPPinit) SPPPsetregion (pinesobj)

Result:


Initializes internal variables for further use in 

point process quantlets.
