Description Usage Arguments Value Author(s) Examples

Solves the differential equations with the optimised and fixed parameters
from a previous successful call to `mkinfit`

and plots
the observed data together with the solution of the fitted model.

If the current plot device is a `tikz`

device,
then latex is being used for the formatting of the chi2 error level,
if `show_errmin = TRUE`

.

`x` |
Alias for fit introduced for compatibility with the generic S3 method. |

`fit` |
An object of class |

`obs_vars` |
A character vector of names of the observed variables for which the data and the model should be plotted. Defauls to all observed variables in the model. |

`xlab` |
Label for the x axis. |

`ylab` |
Label for the y axis. |

`xlim` |
Plot range in x direction. |

`ylim` |
Plot range in y direction. |

`col_obs` |
Colors used for plotting the observed data and the corresponding model prediction lines. |

`pch_obs` |
Symbols to be used for plotting the data. |

`lty_obs` |
Line types to be used for the model predictions. |

`add` |
Should the plot be added to an existing plot? |

`legend` |
Should a legend be added to the plot? |

`show_residuals` |
Should residuals be shown? If only one plot of the fits is shown, the residual plot is in the lower third of the plot? Otherwise, i.e. if "sep_obs" is given, the residual plots will be located to the right of the plots of the fitted curves. |

`maxabs` |
Maximum absolute value of the residuals. This is used for the scaling of the y axis and defaults to "auto". |

`sep_obs` |
Should the observed variables be shown in separate subplots? If yes, residual plots requested by "show_residuals" will be shown next to, not below the plot of the fits. |

`rel.height.middle` |
The relative height of the middle plot, if more than two rows of plots are shown. |

`lpos` |
Position(s) of the legend(s). Passed to |

`inset` |
Passed to |

`show_errmin` |
Should the FOCUS chi2 error value be shown in the upper margin of the plot? |

`errmin_digits` |
The number of significant digits for rounding the FOCUS chi2 error percentage. |

`...` |
Further arguments passed to |

The function is called for its side effect.
