This looks like microarray data for which the Bioconductor project (http://bioconductor.org/biocLite.R) might be useful > source('http://bioconductor.org/biocLite.R') > biocLite() # installs a number of pacakges > biocLite('hgu95av2.db') # a particular chip 'annotation' file > library(hgu95av2.db) > hgu95av2GENENAME[["1053_at"]] [1] "replication factor C (activator 1) 2, 40kDa" > hgu95av2SYMBOL[["1053_at"]] [1] "RFC2" probe id's are keys, with different 'hash'es underneath and non-trivial functionality neatly encapsulated. > openVignette() and then choose AnnotationDbi for additional examples (or via the Bioc web site, following the 'Packages' quick link). Also see the archives and bioc mailing list, mentioned on the site.
