fillDepthCellsWithRoots: Calculates a root mass depth profile

In tilbud/rCTM: R-Cohort Marsh Equilibrium Model

Calculates a root mass depth profile

Description

It will take any root biomass and maximum rooting depth, as well as vectors of minimum and maximum depths. We use predefined equations if rootShape is set to linear or exponential It can also take a custom function of x, as long as you define parameters in a custom parameters list. The custom function listed here is a gaussian root depth distribution.

Usage

fillDepthCellsWithRoots(
  depthMins = 0:149,
  depthMaxs = 1:150,
  totalRootBmass = 3000,
  rootShape = "linear",
  rootDepthMax = 30,
  customFunction = function(x) {     exp(-((x - maxRootDepth)^2/lambdaRoot^2)) },
  customParams = list(lambdaRoot = 33, maxRootDepth = 30)
)

Arguments

depthMins	a vector of numerics, minimum of depth intervals that the function will fill with roots
depthMaxs	a vector of numerics, maximum of depth intervals that the function will fill with roots
totalRootBmass	a numeric, total root biomass
rootShape	a character, either linear, exponential, or custom, defining the shape of the root profile
rootDepthMax	a numeric, maximum depth of root zone
customFunction	a function (optional), if root shape is custom, then use a customized function
customParams	a list (optional), any other parameters required by a custom root shape function

Value

a data frame with minimum and maximum depths and and root biomass within those depths intervals
