r-bioc-genomeinfodb 1.16.0-2 (i386 binary) in ubuntu cosmic

 This package contains BioConductor utilities for manipulating
 chromosome and other 'seqname' identifiers.
 .
 The Seqnames package contains data and functions that define and allow
 translation between different chromosome sequence naming conventions
 (e.g., "chr1" versus "1"), including a function that attempts to place
 sequence names in their natural, rather than lexicographic, order.
