In bcgov/BCForestGroundSample: BC forest ground sample compilation

Description

Calculates species composition at cluster level based on cluster/species summary. The cluster/species-level summaries is an output of volSmry_byCS function. This function is equivalent to sp_comp.sas in original compiler.

Usage

speciesComp_byC(CSSmryTable, basedOn, speciesMaxNO, smallTreeCompile)


  ## S4 method for signature 'data.table,character,numeric,logical'
speciesComp_byC(CSSmryTable,
  basedOn, speciesMaxNO, smallTreeCompile)


  ## S4 method for signature 'data.table,character,numeric,missing'
speciesComp_byC(CSSmryTable,
  basedOn, speciesMaxNO)

Arguments

CSSmryTable	data.table, Summarized volume components for both measured and counted trees at cluster and species level. See volSmry_byCS for details.
basedOn	character, Specifies which component is used for species composition summary.
speciesMaxNO	numeric, Maximum number of species entries to calculate.
smallTreeCompile	logical, Defines whether the function is used for calculate species composition for small trees. If missing, FALSE is used.

Value

A data table that contains species composition at cluster level.
