hguqiagenv3CHR {hguqiagenv3} | R Documentation |
hguqiagenv3CHR is an R environment that provides mappings between a manufacturer id and the chromosome that contains the gene of interest.
Each manufacturer id maps to a vector of chromosomes. Due to
inconsistencies that may exist at the time the environment was built,
the vector may contain more than one chromosome (e.g., the id may map
to more than one chromosome). If the chromosomal location is unknown,
the vector will contain an NA
.
Mappings were based on data provided by:
Entrez Gene:ftp://ftp.ncbi.nlm.nih.gov/gene/DATA/. Built: Source data downloaded from Entrez Gene on Sun Mar 26 01:17:38 2006

# Convert to a list xx <- as.list(hguqiagenv3CHR) # Remove probe ids that do not map to any CHRLOC xx <- xx[!is.na(xx)] if(length(xx) > 0){ # Get the chromosome number for the first five probes xx[1:5] # Get the first one xx[[1]] }
