Utility functions to manage geographical polygons.

Usage

buildPOLYGON(bottomleftcorner, toprighcorner, interactive = FALSE,
             xlim = c(-180, 180), ylim = c(-90, 90))
as.POLYGON(x, y = NULL)
## S3 method for class 'POLYGON'
print(x, ...)
## S3 method for class 'POLYGON'
plot(x, add = FALSE, col = rgb(1, 1, 0, 0.25),
     xlim = NULL, ylim = NULL, around = 1, ...)

Arguments

bottomleftcorner	a numeric vector with two values giving the longitude and latitude (in decimal degrees) of the bottom-left corner of a rectangle.
toprighcorner	id. for top-right corner.
interactive	a logical value. If TRUE, the user is invited to click on a map plotted to define the coordinates of the polygon.
xlim, ylim	the limits of the map.
