chrIndices-methods: Get a matrix of first and last index of features in each...

In genoset: A RangedSummarizedExperiment with methods for copy number analysis

Description

Sometimes it is handy to know the first and last index for each chr. This is like chrInfo but for feature indices rather than chromosome locations. If chr is specified, the function will return a sequence of integers representing the row indices of features on that chromosome.

Usage

chrIndices(object, chr = NULL)

## S4 method for signature 'GenoSetOrGenomicRanges'
chrIndices(object, chr = NULL)

Arguments

object	GenoSet or GRanges
chr	character, specific chromosome name

Value

data.frame with 'first' and 'last' columns

Examples

  data(genoset,package='genoset')
  chrIndices(genoset.ds)
  chrIndices(rowRanges(genoset.ds))  # The same
