## S4 method for signature 'character,numeric,numeric,numeric,missing'
PHFCalculator(sampleType,
  blowUp, treeWeight, plotWeight)

Arguments

sampleType

character, Specifies how the plot is sampled among fixed area plot or variable area plot, must be either V for variable area plot or F for fixed area plot.

blowUp

numeric, Specifies the blowup factor. For fixed area plot, it is calculated as 1/plotarea. For variable area plot, it is basal area factor (BAF).

treeWeight

numeric, Specifies whether a tree is zero counted (tree is out), one time counted (regular count) or two times counted (double counted) in the walk through sampling protocal.

plotWeight

numeric, Specifies how a plot is measured, i.e., full plot measured (valued as 1), half plot measured (valued as 2) or quarter plot measured (valued as 4).

treeBasalArea

numeric, When plot is measured using variable area plot, this value must be given, otherwise, can be missing

Value

Tree per ha factor
