The prepareGenomePlot() function in the quantsmooth package can be used to do that.

Hello,

I would like to plot a list of interesting genes (located on different
chromosomes) on a genome. I extracted their genomic coordinates with
biomaRt (see table below) and now I am looking for a way to send them
all to some plotting function.

So I have a matrix like this:

                  chromosome_name start_position end_position strand band
gene1               1      295038550    295099001     1   H6
gene2               2      8660648    8693244     -1 E3.1
gene3               X       880698     929632     -1   A3
gene4               4       84109214     84109545      1 C1.1
gene5               4       35964995     35982539     -1 C1.2

and now I want to plot all these genes on a genome to have a visual
representation of their position.

I've tried to do this with GenomeGraph, but it seems to allow only for
extraction of all genes/transcripts etc. from a given region of a single
chromosome, and not just from a user-supplied gene list.

Could anyone please suggest a package/way to do this?

thanks,
jarek
