Loess smoothing is applied independently to each cluster of genomic locations. Locations within the same cluster are close together to warrant smoothing across neighbouring locations.

1 2 | ```
loessByCluster(y, x = NULL, cluster, weights = NULL, bpSpan = 1000,
minNum = 7, minInSpan = 5, maxSpan = 1, verbose = TRUE)
``` |

`y` |
A vector or matrix of values to be smoothed. If a matrix, each column represents a sample. |

`x` |
The genomic location of the values in y |

`cluster` |
A vector indicating clusters of locations. A cluster is typically defined as a region that is small enough that it makes sense to smooth across neighbouring locations. Smoothing will only be applied within a cluster, not across locations from different clusters. |

`weights` |
weights used by the loess smoother |

`bpSpan` |
The span used when loess smoothing. (Expressed in base pairs.) |

`minNum` |
Clusters with fewer than |

`minInSpan` |
Only smooth the region if there are at least this many locations in the span. |

`maxSpan` |
The maximum span. Spans greater than this value will be capped. |

`verbose` |
Boolean. Should progress be reported? |

This function is typically called by `smoother`

, which is in
turn called by `bumphunter`

.

`fitted ` |
The smoothed data values |

`smoothed ` |
A boolean vector indicating whether a given position was smoothed |

`smoother ` |
always set to ‘loess’. |
