Description Usage Arguments Value Author(s) See Also Examples

This function creates a model for one pool. It is a wrapper for the more general function `GeneralModel_14`

``` |

`t` |
A vector containing the points in time where the solution is sought. It must be specified within the same period for which the Delta 14 C of the atmosphere is provided. The default period in the provided dataset |

`k` |
A scalar with the decomposition rate of the pool. |

`C0` |
A scalar containing the initial amount of carbon in the pool. |

`F0_Delta14C` |
A scalar containing the initial amount of the radiocarbon fraction in the pool in Delta_14C format. |

`In` |
A scalar or a data.frame object specifying the amount of litter inputs by time. |

`xi` |
A scalar or a data.frame specifying the external (environmental and/or edaphic) effects on decomposition rates. |

`inputFc` |
A Data Frame object consisting of a function describing the fraction of C_14 in per mille. The first column will be assumed to contain the times. |

`lambda` |
Radioactive decay constant. By default lambda=-0.0001209681 y^-1 . This has the side effect that all your time related data are treated as if the time unit was year. |

`lag` |
A (positive) scalar representing a time lag for radiocarbon to enter the system. |

`solver` |
A function that solves the system of ODEs. This can be |

`pass` |
if TRUE Forces the constructor to create the model even if it is invalid |

A Model Object that can be further queried
