## Highlights data points in a plotted profile to evaluate filtering

### Description

Highlights data points in a plotted profile to evaluate filtering.

### Usage

    highlightFilters(object, col="red", residual=NA, blacklist=NA, mappability=NA, bases=NA,
      type="union", ...)

### Arguments

`object` | A `QDNAseqCopyNumbers` object.
`col` | The color used for highlighting.
`residual` | Either a `logical` specifying whether to filter based on loess residuals of the calibration set, or if a `numeric`, the cutoff as number of standard deviations estimated with `madDiff` to use for. Default is `TRUE`, which corresponds to 4.0 standard deviations.
`blacklist` | Either a `logical` specifying whether to filter based on overlap with blacklisted regions, or if numeric, the maximum percentage of overlap allowed. Default is `TRUE`, which corresponds to no overlap allowd (i.e. value of 0).
`mappability` | A `numeric` in [0,100] to specify filtering out bins with mappabilities lower than the number specified. NA (default) or `FALSE` will not filter based on mappability.
`bases` | A `numeric` specifying the minimum percentage of characterized bases (not Ns) in the reference genome sequence. NA (default) or `FALSE` will not filted based on uncharacterized bases.
`type` | When specifying multiple filters (`residual`, `blacklist`, `mappability`, `bases`), whether to highlight their `union` (default) or `intersection`.
`...` | Further arguments to `points`.
