Description Usage Arguments Value Examples
straightness
compute a straightness index between 0 and 1 by making the
ration L / l
where L
is the cumulated distance between
brokenstick points and and where l
the cumulated distance between
each y
data points.

sinuosity(x, y = NULL, npts = 3)

x |
The x data (time). |
y |
The y data (depth). |
npts |
The number of points to use. 2 is the minimum (from the start
to the end of data). Each new point adds a step (using the |
straightness
returns a number between 0 (maximum sinuosity)
to 1 (maximum straightness). sinuosity
is equivalent to
1 / straightness
