  epoch.length, dataset)

Arguments

speed.cutoff	The cut-off above which speed is deemed unreliable, in the same units as your speed variable
hdop.cutoff	The cut-off above which your horizontal dilution of precision is deemed unreliable
neighbour.number	an integer: if you are removing isolated points, how few neighbours counts as isolated
