## S4 method for signature 'RangedSummarizedExperiment'
coverage(x, shift=0L, width=NULL, weight=1L,
            method=c("auto", "sort", "hash"))

`x`	A RangedSummarizedExperiment object.
`shift, width, weight, method`	See `?coverage` in the GenomicRanges package.

This method operates on the rowRanges component of the RangedSummarizedExperiment object, which can be a GenomicRanges or GRangesList object.

More precisely, on RangedSummarizedExperiment object x, coverage(x, ...) is equivalent to coverage(rowRanges(x), ...).

See ?coverage in the GenomicRanges package for the details of how coverage operates on a GenomicRanges or GRangesList object.

See ?coverage in the GenomicRanges package.
