# Function to compute auto-correlation of probe intensities

### Description

Function to compute auto-correlation of probe intensities at specified offsets from the original positions.

### Usage

1 2 3 4 |

### Arguments

`x` |
an object either of class |

`probeAnno` |
Object of class |

`chrom` |
character; chromosome to compute the autocorrelation for |

`samples` |
which samples of the data to use; if more than 1 for each probe the mean intensity over these samples is taken. |

`lag.max` |
integer; maximal offset from the original position, the auto-correlation is to be computed for. |

`lag.step` |
integer; step size of lags between 0 and maximal lag. |

`cor.method` |
character; which type of correlation to compute,
translates to argument |

`channel` |
character; in case |

`idColumn` |
string; indicating which column of the |

`verbose` |
logical; extended output to STDOUT |

### Details

the lags, i.e. the offsets from the original position, the
auto-correlation is to be computed for, are constructed from the
given arguments as `seq(0, lag.max, by=lag.step)`

.

### Value

Object of class `autocor.result`

, a
numeric vector of auto-correlation values at the offsets specified in
argument `lags`

. The lag values are stored as the `names`

of
the vector. Argument `chrom`

is stored as attribute
`chromosome`

of the result.
