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

Tutorial: Spatial statistics

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:

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

Result:

Initializes internal variables for further use in
point process quantlets.
