  base = "base",
  top = "top",
  he = "he",

  wid = "width",
  Site = "Site",
  sN = "SiteName",
  negEx = 1,
  max = 54.22,
  rate = 0.026,
  a = 3.35,
  b = 0.832,
  age = NA,
  surf = 10,
  density = 300,
  cover = 0.8,
  aQ = NA,
  bQ = NA,
  cQ = NA,
  maxNS = NA,
  rateNS = NA,
  wNS = 1,
  thin = TRUE,
  sLit = TRUE,
  dec = TRUE,
  sepSig = 0.001,
  messages = F,
  overlap = 0.5
)

Arguments

`dat`	The dataframe containing the formatted field survey data
`default.species.params`	Plant traits database
`pN`	The number of the point in the transect
`spName`	Name of the field with the species name
`base`	Name of the field with the base height
`top`	Name of the field with the top height
`he`	Name of the field with dimension he
`ht`	Name of the field with dimension ht
`wid`	Name of the field with dimension width
`Site`	Name of the field with the record number
`sN`	Optional field with a site name
`negEx`	Value determining the model used. 1 = olson, 2 = Burr
`max`	Maximum weight of surface litter (t/ha)
`rate`	Growth rate for surface litter in a negative exponential function
`a`
`b`
`age`	Optional field with site age
`surf`	Weight of surface litter in t/ha
`density`	Wood density (kg.m-3)
`cover`	Percent cover of suspended layer
`aQ`	Parameter for a quadratic trend; leave as NA if trend is negative exponential
`bQ`	Parameter for a quadratic trend; leave as NA if trend is negative exponential
`cQ`	Parameter for a quadratic trend; leave as NA if trend is negative exponential
`maxNS`	Parameter for a negative exponential trend; leave as NA if trend is quadratic
`rateNS`	Parameter for a negative exponential trend; leave as NA if trend is quadratic
`wNS`	Width of near surface patches (m)
`thin`	Logical - TRUE uses plant self-thinning models in Dynamics, otherwise plant cover remains at the highest point it has reached by that age
`sLit`	Logical - TRUE allows surface litter to decline if the model does so, otherwise the maximum value to that age is maintained
`dec`	Logical - TRUE allows near surface surface litter to decline if the model does so, otherwise
`sepSig`
`messages`	T or F to display messages from component functions
`overlap`	Either 'automatic', or threshold occurrence at which overlap is set to TRUE. the maximum value to that age is maintained
