check_format_roots_data: Prepare the root parameters for use un the Soil Water Balance...

In EcoFoG/SWBM: REW computation for Paracou with the Soil Water Balance Model (Wagner et al 2011).

Description

This function takes sampled root proportion among layers as an input dataset, and uses a negative exponential function (/codeRfd_l = /lambda e^-lambda*l) to estimate the distribution of fine roots among the soil, at a 1cm resolution.

Usage

check_format_roots_data(
  roots_data,
  layer_init_col = "depth_layer_init",
  layer_end_col = "depth_layer_end",
  percent_col = "percentRoots"
)

Arguments

roots_data	data.frame, containing one-line-per-layer fine roots percentages percentage as well as upper and lower depth bounds of the sampled layers (always positive numbers: low values being close to the surface, and high value being deep)
layer_init_col	character, the name of the column containing upper (close to the surface) end depth for each layer
layer_end_col	character, the name of the column containing lower (far from the surface) end depth for each layer
percent_col	character, the name of the column containing observed fine roots percentage for each layer (percents, i.e. the sum of the column is 1)

Value

a list containing two elements, the first a data.frame containing modelled fine roots density for each 1cm sublayer, as well as information on
