BigWigSelection-class {rtracklayer} | R Documentation

## 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 `IntegerRangesList`, 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 `IntegerRangesList`, the ranges of which become the ranges in the new `BigWigSelection`.

### Examples

      rl <- IRangesList(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())
