flowlength
(Package: topmodel) :
Calculates the flow distance towards the catchment outlet
Given a digital elevation model and the coordinates of the catchment outlet, this function calculates the flowlength of each gridcell to the outlet, based on a single flow direction algorithm (D8).

make.classes
(Package: topmodel) :
make topographic index classes from a topographic index map
This function splits a dataset in n evenly distributed classes and calculates the number of elements of each class. It is very similar to hist(), but hist() does not always keep the number of breaks requested

river
(Package: topmodel) :
Identification of rivers in a digital elevation model
This function identifies river headwater cells based on threshold values in a topographic index and accumulated area river (generated using topidx. Rivers are then traced downslope using a single flow algorithm.
