getChromosome: Grab a specific chromosome

In aryeelab/sparseHiC: Efficient compression and analysis of Hi-C Data

Description

getChromosome takes a sparseHiCdatum object and returns a list of sparse Hi-C matrices. If a list is returned, then the names are the resolutions. If the length of chr > 1 (multiple chromosomes), then a list of lists will be returned if a.list is TRUE

Usage

getChromosome(obj, chr, a.list = TRUE)

## S4 method for signature 'sparseHiCdatum,character'
getChromosome(obj, chr, a.list = TRUE)

Arguments

obj	A sparseHiCdatum object
chr	Chromosome(s) desired
a.list	= TRUE Return a list of matrices? If FALSE, return another sparseHiCdatum object

Value

Returns object subsetted by resolution

Examples

chr <- "chr21"
rds<-paste(system.file('rds',package='sparseHiC'),'hESCdatum1.rds',sep='/')
hESCdatum1 <- readRDS(rds)
r <- getChromosome(hESCdatum1,chr = chr, a.list = FALSE)
