[BioC] Plot: expression by location start AND stop

[Daniel Brewer]

Another plot question I am afraid.  Thanks for all the help with the
previous one.
I have the expression levels of a number of exons in a gene.  I would
look like to see how the expression levels vary across the gene.  For
each of the exons I have a start position and a stop position.

It is easy enough to plot the expression level verses the start/stop
position:
> plot(exonAnnot[rownames(temp),names(exonAnnot)=="start"],temp[,16], main=names(temp)[16])

where temp is the expression matrix for the relevant exons.

What I would like to do is for each exon draw a bar from the start
position to the stop position at the level of expression.

Anyway to do this?

Many thanks

Dan
