R2G2 (version 1.0-2)

FancyPies: Computes the edges of any regular n-sided figure in spherical coordinates and adds a pie chart within it

Description

Provides coordinates for one pie chart, this function must be iterated to produce several pies.

Usage

FancyPies(center, obs, nedges = 3, radius = 5e4, orient = 0, diag = FALSE)

Arguments

center

The geographical position of the pie as c(lon, lat) in decimal degrees.

obs

Vector of numerical and non-negative quantities that will be displayed as the pie slices (typically produced using table()).

nedges

The number of desired edges (3 -> triangle, 4 -> square, etc).

radius

The pie radius (in meters).

orient

The rotation factor of the fig (in degrees).

diag

Produce diagnostic plot for checking purposes (True or False).

Value

Provides an array of coordinates for drawing the pie chart as polygons (lines = points delimiting the pie sectors, columns = sector number, lon, lat in decimal degrees).

Details

This function is wrapped within Pies2GE; see below.
