A.5 Restricting Ranges

The verb filter can be used to restrict rows in the Ranges. Note that grouping will cause the filter to act within each group of the data.

#> GRanges object with 2 ranges and 1 metadata column:
#>       seqnames    ranges strand |        gc
#>          <Rle> <IRanges>  <Rle> | <numeric>
#>   [1]     chr2      2-11      + |  0.180407
#>   [2]     chr1      5-14      - |  0.130289
#>   -------
#>   seqinfo: 2 sequences from an unspecified genome; no seqlengths

#> GRanges object with 2 ranges and 1 metadata column:
#> Groups: strand [2]
#>       seqnames    ranges strand |        gc
#>          <Rle> <IRanges>  <Rle> | <numeric>
#>   [1]     chr2      1-10      - |  0.889454
#>   [2]     chr2      4-13      + |  0.989564
#>   -------
#>   seqinfo: 2 sequences from an unspecified genome; no seqlengths

We also provide the convenience methods filter_by_overlaps and filter_by_non_overlaps for restricting by any overlapping Ranges.
