Calculating the percentage of canopy in the entire mosaic or per plot using the fieldShape file

Usage

  canopy(mosaic, canopyValue=0, fieldShape=NULL, n.core=NULL, plot=T)

Arguments

mosaic	object mask of class stack from the function fieldMask().
canopyValue	referent value of canopy in the image.
fieldShape	evaluate the canopy percentage per plot using the fieldShape as reference. If fieldShape=NULL, the canopy percentage will be calculated directly for the entire original image.
n.core	number of cores to use for multicore processing (Parallel).
