IRanges (version 2.6.1)

IRangesList-class: List of IRanges and NormalIRanges


IRangesList and NormalIRangesList objects for storing IRanges and NormalIRanges objects respectively.



IRangesList(..., universe = NULL, compress = TRUE): The ... argument accepts either a comma-separated list of IRanges objects, or a single LogicalList / logical RleList object, or 2 elements named start and end each of them being either a list of integer vectors or an IntegerList object. When IRanges objects are supplied, each of them becomes an element in the new IRangesList, in the same order, which is analogous to the list constructor. If compress, the internal storage of the data is compressed.


unlist(x): Unlists x, an IRangesList, by concatenating all of the ranges into a single IRanges instance. If the length of x is zero, an empty IRanges is returned.

Methods for NormalIRangesList objects

max(x): An integer vector containing the maximum values of each of the elements of x.
min(x): An integer vector containing the minimum values of each of the elements of x.

Run this code
  range1 <- IRanges(start=c(1,2,3), end=c(5,2,8))
  range2 <- IRanges(start=c(15,45,20,1), end=c(15,100,80,5))
  named <- IRangesList(one = range1, two = range2)
  length(named) # 2
  names(named) # "one" and "two"
  named[[1]] # range1
  unnamed <- IRangesList(range1, range2)
  names(unnamed) # NULL

  x <- IRangesList(start=list(c(1,2,3), c(15,45,20,1)),
                   end=list(c(5,2,8), c(15,100,80,5)))
