cs

Cell size (in degree lat, long). Default is 0.5 degree long by 0.5 degree lat. In this region, 1 deg latitude ~= 69 miles & 1 deg longitude ~= 55 miles. The total length of a BBS route is ~50 miles. Caution when using degrees < 1 by 1 degree as a single route could fal into multiple cells...

bbLat

Min and max (in any order) latitude coordinates for the bounding box. The function removes routes (lat,long) falling outside these coordinates. Default = c(23, 51). See also 'bbLong'.

bbLong

Min and max (in any order) longitude for the bounding box. The function removes routes (lat,long) falling outside these coordinates. Default = c(23, 51). See also 'bbLat'.
