Brick_matrix_dimensionsR Documentation

Return the dimensions of a matrix

Description

Return the dimensions of a matrix

Usage

Brick_matrix_dimensions(Brick, chr1, chr2, resolution = NA)

Arguments

Brick

Required. A string specifying the path to the Brick store created with Create_many_Brick.

chr1

Required. A character vector of length 1 specifying the chromosome corresponding to the rows of the matrix

chr2

Required. A character vector of length 1 specifying the chromosome corresponding to the columns of the matrix

resolution

Optional. Default NA When an object of class BrickContainer is provided, resolution defines the resolution on which the function is executed

Value

Returns the dimensions of a Hi-C matrix for any given chromosome pair.

Examples


Bintable.path <- system.file(file.path("extdata", "Bintable_100kb.bins"), 
package = "HiCBricks")

out_dir <- file.path(tempdir(), "matrix_dimension_test")
dir.create(out_dir)

My_BrickContainer <- Create_many_Bricks(BinTable = Bintable.path, 
    bin_delim = " ", output_directory = out_dir, file_prefix = "Test",
    experiment_name = "Vignette Test", resolution = 100000,
    remove_existing = TRUE)

Matrix_file <- system.file(file.path("extdata", 
"Sexton2012_yaffetanay_CisTrans_100000_corrected_chr2L.txt.gz"), 
package = "HiCBricks")

Brick_load_matrix(Brick = My_BrickContainer, chr1 = "chr2L", 
chr2 = "chr2L", matrix_file = Matrix_file, delim = " ", 
remove_prior = TRUE, resolution = 100000)

Brick_matrix_dimensions(Brick = My_BrickContainer, chr1 = "chr2L", 
chr2 = "chr2L", resolution = 100000)
