remove.outliers.from.raster.IQR(ras, rad = 5, low.perc = 0.25,
high.perc = 0.75, fac = 1.5, high = T, low = T)
``` |

`ras` |
Input raster |

`rad` |
Radius of the considered (circular) neighborhood |

`low.perc` |
Lower end of the desired interquantile range (fraction between 0 and 1) |

`high.perc` |
Upper end of the desired interquantile range (fraction between 0 and 1) |

`fac` |
Factor by which a pixel value needs to exceed or subceed the IQR of its neighbors to be considered an outlier |

`high` |
bool if false high outliers will not be removed |

`low` |
bool if false low outliers will not be removed |
