Loads a named intervals set

Loads a named intervals set.

gintervals.load(
  intervals.set = NULL,
  chrom = NULL,
  chrom1 = NULL,
  chrom2 = NULL
)

Arguments

intervals.set

name of an intervals set

chrom

chromosome for 1D intervals set

chrom1

first chromosome for 2D intervals set

chrom2

second chromosome for 2D intervals set

Value

A data frame representing the intervals.

Details

This function loads and returns intervals stored in a named intervals set.

If intervals set contains 1D intervals and 'chrom' is not 'NULL' only the intervals of the given chromosome are returned.

Likewise if intervals set contains 2D intervals and 'chrom1', 'chrom2' are not 'NULL' only the intervals of the given pair of chromosomes are returned.

For big intervals sets 'chrom' parameter (1D case) / 'chrom1', 'chrom2' parameters (2D case) must be specified. In other words: big intervals sets can be loaded only by chromosome or chromosome pair.
