rmAmbigMappings: Remove genes that map to multiple chromosomes from a chromLocation object

Description

Due to the automated probe annotation, a subset of probes can be “confidently” mapped to multiple chromosomes on the genome.

This can cause some confusion if you are trying to perform certain types of data analysis.

This function examines a chromLocation object and removes probes that map to multiple chromosomes.

Usage

rmAmbigMappings(cL)

Arguments

cL

an existing chromLocation object

Value

A chromLocation object

#if (require(hu6800)) {

#  library(Biobase)
#  library(annotate)

  ## Build a specific chrom arm

#  cL <- buildChromLocation("hu6800")
#  cleanCL <- rmAmbigMappings(cL)
#}
