[BioC] rtracklayer bed import

[Christian Ruckert]

When trying to import the example .bed track from 
http://genome.ucsc.edu/goldenPath/help/customTrack.html#BED with the 
import function from rtracklayer package I get the following error message:

 > tr = import("example.bed")
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, 
na.strings,  :
