exportTracks: Export GenomeGraph tracks to a annotation file...
In Gviz: Plotting data and annotation information along genomic coordinates

Description Usage Arguments Details Value Author(s) Examples

This function is still a bit experimental. So far only BED export is supported.

1	exportTracks(tracks, range, chromosome, file)

`tracks`	A list of annotation track objects to be exported into a single BED file.
`range`	A numeric vector or length 2. The genomic range to display when opening the file in a browser.
`chromosome`	The chromosome to display when opening the file in a browser.
`file`	Character, the path to the file to write into.

FIXME: Need to support WIG exports as well...

The function is called for its side effect of writing to a file.

## export AnnotationTrack to BED file
at <- AnnotationTrack(start=seq(1,10), width=1, chromosome="chr1")
exportTracks(list(at), range=c(1, 10), chromosome="chr1", 
             file=paste0(tempfile(),".bed"))
