This function adds new points to a
A space-time object of class “
A vector, data frame, matrix or list of points to be added to
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.
add.stpoints returns an object of class “
1 2 3 4 5 6 7 8 9 10 11 12 13
