mpspline_fit1

Fit spline parameters to data for a single site.

internal

A low-dependency implementation of GSIF::mpspline() <https://r-forge.r-project.org/scm/viewvc.php/pkg/R/mpspline.R?view=markup&revision=240&root=gsif>,
which applies a mass-preserving spline to soil attributes. Splining soil data
is a safe way to make continuous down-profile estimates of attributes measured
over discrete, often discontinuous depth intervals.

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