Hi, The illuminaRatv1.db package has a dependency error in bioconductor version > 2.10. The org.Rn.eg.db dependency has been replaced with org.Hs.eg.db. illuminaRatv1.db will fail on load without org.Rn.eg.db with error meassge along the lines of (reported from customer): Error : .onLoad failed in loadNamespace() for 'illuminaRatv1.db', details: call: sqliteExecStatement(con, statement, bind.data) error: RS-DBI driver: (error in statement: no such table: chrlengths) Error: package/namespace load failed for 'illuminaRatv1.db' For people searching the list for solutions: Install org.Rn.eg.db prior to illuminaRatv1.db and you are good to go. best regards, Arnar --------------------- Arnar Flatberg Genomics Core Facility Norwegian Institute of Science and Technology Trondheim, Norway [[alternative HTML version deleted]]
