Plotting spatial blocks borders

	# This procedure allows to plot blocks borders
	# over some spatially-arranged variable

	# Data is assumed to be on a regular grid
	# The dataset contains row and column coordinates
	# a numerical variable indicating the block number of the current cell
	# and the numerical variable to be plotted

	# Requirements:
	# either package rgeos, which depends on [GEOS](http://trac.osgeo.org/geos/) (GEometry Open Source)

Counting the number of points in each cell of a regular grid

	library(ggplot2)

	# Some fake points
	N <- 500
	loc <- matrix(runif(2*N), ncol=2)

	# A regular (not necessarily square) grid
	n.row <- 10
	n.col <- 10
	xrange <- range(loc[,1])
