A slow trimmed mean smoother (using R code) of data at discrete points (e.g. probe-level data).

1 | ```
trimmedMean(pos, score, probeWindow=600, meanTrim=.1, nProbes=10)
``` |

`pos` |
numeric vector of positions (x-values) |

`score` |
numeric vector of data (corresponding to |

`probeWindow` |
distance (in x) in each direction to look for observations to be used in the trimmed mean |

`meanTrim` |
proportion of trim to use in trimmed mean |

`nProbes` |
minimum number of observations required within window |

Using the specified probe window, this procedure uses all values within the window and calculates a trimmed mean with the specified amount of trim. If there are not enough observations within the window at a given position (as given by `nProbes`

), a zero is returned.

vector (of the same length as `sp`
