BigWigSelection-class: Selection of ranges and columns

Description

A BigWigSelection represents a query against a BigWig file, see import.bw. It is simply a RangedSelection that requires its colnames parameter to be "score", if non-empty, as that is the only column supported by BigWig.

Constructor

BigWigSelection(ranges = GRanges(), colnames = "score"): Constructs a BigWigSelection with the given ranges and colnames. ranges can be either something coercible to a RangesList, a character identifying a genome (see GenomicSelection), or a BigWigFile, in which case the ranges are derived from the bounds of its sequences.

Coercion

as(from, "BigWigSelection"): Coerces from to a BigWigSelection object. Typically, from is a GRanges or a RangesList, the ranges of which become the ranges in the new BigWigSelection.

Examples

  rl <- IRanges::RangesList(chr1 = IRanges::IRanges(c(1, 5), c(3, 6)))

  BigWigSelection(rl)
  as(rl, "BigWigSelection") # same as above

  # do not select the 'score' column
  BigWigSelection(rl, character())
