Description Usage Arguments Value Examples
This function uses the equations laid out in Pataki et al, 2011 to calculate the total sap flow of a tree from sap flux measurements in the outer sapwood. It assumes a 2 cm long sapflux probe and silently considers the total stem area to be sapwood area if the sapwood area is greater than the area of the tree caluclated form the diameter argument.
