The name of the hull metric used as a proxy for directionality |

The threshhold above which a hull is considered part of a directional route |
thresh.type |
The type of thresshold used. If |
smooth |
The amount of temporal smoothing applied, expressed as the number of points on either side (temporally) of the parent
point whose average of the directionality metric is used for determining if the hull constructed around the parent point should be considered a part of a directional route.

Whether to display histogram(s) of the distribution of the directionality metric before and after smoothing. T/F |
A LoCoH-hullset object
Directional routes are line segments defined by connecting temporally contiguous hull parent-points that are in the top N percent of hull elongation.
Hull elongation is proxied by one of two hull metrics: perimeter:area ratio ('par') or the eccentricity of the bounding ellipse ('ecc'). Hull perimeter:area ratios
are automatically computed when a hullset is created; bounding ellipses must be computed separately using lhs.ellipses.add
.
Once computed, you can plot directional routes by passing dr=TRUE
to plot.locoh.lhs
.
