Description Usage Arguments Examples

Graphical quality control test of extracted slopes represents a visual comparison of linear regression of corrected *O_{2}* concentration over time with current and alternative length of measurements.

`slope.data` |
a data frame obtained by using the function |

`clean.data` |
a data frame obtained by using the function |

`chamber` |
string: the chamber chosen for the QC test |

`current` |
integer: current length of measurements for slope estimation (in seconds, black line) |

`alter` |
integer: alternative length of measurements for slope estimation (in seconds, red line) |

`residuals` |
logical: if TRUE then regression diagnostic graphs are plotted for each slope estimation (black graphs: for current slope estimation; red graphs: for alternative slope estimation). More information on diagnostic graphs can be found in the documentation of the function |
