FcAtm.from.Dataframe

This function is deprecated constructor of the deprecated class FcAtm

Functions for modeling Soil Organic Matter decomposition
in terrestrial ecosystems with linear and nonlinear systems of differential equations.
The package implements
models according to the compartmental system representation described in
Sierra and others (2012) <doi:10.5194/gmd-5-1045-2012> and Sierra and others (2014)
<doi:10.5194/gmd-7-1919-2014>.

FcAtm.from.Dataframe function

<dl><dt>dframe</dt>
<dd>A data frame containing exactly two columns: the first one is
interpreted as time the second one is interpreted as atmospheric C14 fraction
in the format mentioned</dd>
<dt>lag</dt>
<dd>a scalar describing the time lag. Positive Values shift the
argument of the interpolation function forward in time. (retard its effect)</dd>
<dt>interpolation</dt>
<dd>A function that returns a function the default is
splinefun. Other possible values are the linear interpolation approxfun or
any self made function with the same interface.</dd>
<dt>format</dt>
<dd>a string that specifies the format used to represent the
atmospheric fraction. Possible values are "Delta14C" which is the default or
"afn" the Absolute Fraction Normal representation</dd></dl>
