Detect Multiple Routes

Called internally within riverdistancelist. Detects all possible routes from one river network segment to another, in the event of braiding.

routelist(startseg, endseg, rivers, reps = 100)

Arguments

startseg	Segment number of the start of the route
endseg	Segment number of the end of the route
rivers	The river network object to use
reps	Deprecated. Was used in a previous version using randomization.

Value

A list of vectors, each describing a route in segment numbers.

Note

The previous version of this function returned many possible routes using randomization - this algorithm now computes all possible routes.

Examples

data(KilleyW)
plot(x=KilleyW)

routelist(startseg=1, endseg=16, rivers=KilleyW, reps=1000)
