proportion_silhouette_area_shapes {TrenchR} | R Documentation |
The function estimates the projected (silhouette) area as a portion of the surface area of the organism. The function estimates the projected area as a function of the dimensions and the angle between the solar beam and the longitudinal axis of the solid, using Figure 11.6 in Campbell and Norman (1998). The function is useful for estimating absorbed solar radiation.
