Hi Paul,

The org.*.eg.db annotation packages provide mappings from gene IDs to their
location in the genome:


If you are new to Bioconductor annotations, a must-read is the vignette in
the AnnotationDbi package + the man page of the particular map you want to
use (probably org.*.egCHRLOC and org.*.egCHRLOCEND in your case).
