netVolumeCalculator: Calcualtes total net volume and merchantable volume-VRI...

In bcgov/BCForestGroundSample: BC forest ground sample compilation

Description

This function calculates total net volume and net merchantable volume for each tree based on ground called sound percentage. From the second column to the last column, the grossVolMatrix table should have same dimensions (i.e., number of rows and columns) of netFactorMatrix and grossMerchVolMatrix if they are provided. Furthermore, be aware of the correspondingness among the matrix. This function is part of log_valu_2017.sas.

Usage

netVolumeCalculator(grossVolMatrix, grossMerchVolMatrix, netFactorMatrix)


  ## S4 method for signature 'data.table,data.table,data.table'
netVolumeCalculator(grossVolMatrix,
  grossMerchVolMatrix, netFactorMatrix)


  ## S4 method for signature 'missing,data.table,data.table'
netVolumeCalculator(grossMerchVolMatrix,
  netFactorMatrix)


  ## S4 method for signature 'data.table,missing,data.table'
netVolumeCalculator(grossVolMatrix,
  netFactorMatrix)


  ## S4 method for signature 'data.table,data.table,missing'
netVolumeCalculator(grossVolMatrix,
  grossMerchVolMatrix)

Arguments

grossVolMatrix	data.table, Calculated gross volume for each log. The first column of this table is the volume for the stump. If missing, the function calculates the total net merchantable volume.
grossMerchVolMatrix	data.table, Calculated gross merchantable volume for each log. If missing, all the merchantable volume is assigned as 0.
netFactorMatrix	data.table, Ground call for sound percentage. If missing, the net factoring will be assigned as 100.

Value

Data table that contains total net volume (VOL_NET) and total net merchantable volume (VOL_NETM) for each tree.
