c_seglengths computes the summed segment length equivalent to nat::seglengths(sumsegment = T)

c_total_cable computes the summed total cable for a whole neuron. It's intended use is the nat::summary.neuron function.

c_seglengths(sl, x, y, z)

c_total_cable(sl, x, y, z)



A seglist with 1-indices into vectors x,y,z

x, y, z

Numeric vectors with 3D coordinate data (which could be columns from a data frame)
