xcol	the name of the column containing the x coordinate
ycol	the name of the column containing the y coordinate
weight	name of column containing data with which to weight the points
radius	the radius of the circle to sweep with (in metres)
inc_data	logical. Whether or not to include the original data alongside the indices of the points included in each circle
