| mgu74bACCNUM {mgu74b} | R Documentation |
mgu74bACCNUM is an R environment that contains mappings between a manufacturer's ids and GenBank accession numbers.
This environment was produced by first mapping the manufacturer's ids to Entrez Gene identifiers http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene. The mapped Entrez Gene ids then serve as the point of linkage to the GenBank accession numbers.
Each manufacturer id maps to a vector containing a GenBank accession number.

# Convert to a list
xx <- as.list(mgu74bACCNUM)
# Remove probe ids that do not map to any ACCNUM
xx <- xx[!is.na(xx)]
if(length(xx) > 0){
# Get the ACCNUM for the first five probes
xx[1:5]
# Get the first one
xx[[1]]
