Create an object of class point from a data frame.
An object of class point represents the observed data of a spatial process. This includes the spatial location of sampling sites and the values observed at those sites. A point object is stored as a data frame. The data frame must contain one column for the X coordinate and one column for the Y coordinate of each point, as well as any number of columns representing data observed at the points.
