Point Objects

Description

Creates and tests for data in spatial point format.

Usage

spoints(data,npoints)

Arguments

data

vector containing the data values for the points in order (x1,y1),(x2,y2),...

npoints

number of points to generate, if missing, set to length(data)/2.

Value

spoints returns an object suitable for use as a point data object. If npoints is given, the vector data is either truncated or repeated until sufficient data values are generated. The returned object is a two-column matrix, where the first column stores the x-coordinate, and the second column stores the y-coordinate.
