Hi, I had a set of regions (e.g. 'chr7:94282859-94288530') from hg18 that I want to convert to hg19. Is there a way that I can do this in rtracklayer (or any other package)? thanks! [[alternative HTML version deleted]]

Use import.chain to bring in a UCSC chain file and then call the liftOver function. See ?liftOver. This is a lot faster than the UCSC executable (in my tests), and it has a commercial-friendly license.
