Autocorrelation in ChIP-chip data. An example data set on histone-3-acetylation, which is provided as part of the software documentation, is used to demonstrate the package's autocorrelation plot. For each base-pair offset d, it assesses how strong the intensities of probes mapped to genomic positions x + d are correlated with the probe intensities at positions x. The computed correlation is plotted against the offset.
