gahgu133bGENESTART {gahgu133b} | R Documentation |
gahgu133bGENESTART is an R environment that provides mappings between a custom probeset identifier and the base pair starting position of gene onto corresponding chromosome.
Each identifier maps to a gene start position.
If the gene start position is unknown,
the vector will contain an NA
.
Mappings were based on data provided by:
GeneCards database - www.genecards.org

# Convert to a list xx <- as.list(gahgu133bGENESTART) # Remove probe identifiers that do not map to any gene start position xx <- xx[!is.na(xx)] if(length(xx) > 0){ # Get the base pair number for gene start position for the first five probes xx[1:5] # Get the first one xx[[1]] }
