gahgu133bSTRAND {gahgu133b} | R Documentation |
gahgu133bSTRAND is an R environment that provides mappings between a custom probeset identifier and the strand of gene onto corresponding chromosome.
Each identifier maps to a gene strand.
If the gene strand 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(gahgu133bSTRAND) # Remove probe identifiers that do not map to any strand xx <- xx[!is.na(xx)] if(length(xx) > 0){ # Get the base pair number for gene strand for the first five probes xx[1:5] # Get the first one xx[[1]] }
