Description

This function adds new points to a stpp object.

Usage

Arguments

X

A space-time object of class “stpp” to add points to.

points

A vector, data frame, matrix or list of points to be added to X.

Details

points can be a vector of length three describing one x, y, and t coordinate, or a matrix or data frame where the first column is a column of x coordinates, the second column is a column of y coordinates, and the third column is a column of t coordinates. If points is a list, the first entry is a vector of x coordinates, the second entry is a vector of y coordinates, and the third entry is a vector of t coordinates.

Value

add.stpoints returns an object of class “stpp”.
