mpspline_fit1: Fit spline parameters

In mpspline2: Mass-Preserving Spline Functions for Soil Data

Fit spline parameters

Description

Fit spline parameters to data for a single site.

Usage

mpspline_fit1(
  s = NULL,
  p = NULL,
  var_name = NULL,
  d = NULL,
  vhigh = NULL,
  vlow = NULL
)

Arguments

s	data.frame; data for one site
p	list; estimated spline parameters for one site from mpspline_est1
var_name	length-1 character or length-1 integer denoting the column in obj in which target data is stored. If not supplied, the fourth column of the input object is assumed to contain the target data.
d	sequential integer vector; denotes the output depth ranges in cm. Defaults to c(0, 5, 15, 30, 60, 100, 200) after the GlobalSoilMap specification, giving output predictions over intervals 0-5cm, 5-15cm, etc.
vhigh	numeric; constrains the maximum predicted value to a realistic number. Defaults to 1000.
vlow	numeric; constrains the minimum predicted value to a realistic number. Defaults to 0.

Value

list of two vectors: fitted values at 1cm intervals and the average of same over the requested depth ranges.
