DNAseUCSC: Creation of an UCSC's DNase clusters track

Description

Creation of DNase cluster track from a connection to UCSC genome browser in using the GViz bioconductor package

Usage

DNAseUCSC(gen, chr, start, end, mySession, track.name = "DNase Clusters", table.name = NULL)

Arguments

gen

the name of the genome

chr

the chromosome of interest

start

the first position in the region of interest (the smallest value)

end

the last position in the region of interest (the largest value)

mySession

the object session from the function browserSession of rtracklayer

track.name

the name of the track DNAseUCSC. "DNase Clusters"(default)

table.name

the name of the table from the track

Value

An AnnotationTrack object of Gviz
