Hi, I'm trying to make a chromosomal map in R by using the locus. I have a list of genes and their locus, and I want to visualise that so you can see if there are multiple genes on a specific place on a chromosome. A example of what I more or less want is below: http://www.nabble.com/file/p21474206/untitled.JPG untitled.JPG The genes and locus are here: http://www.nabble.com/file/p21474206/genlocus.csv genlocus.csv I've tried some things, but nothing worked like I would like it to see. Maybe there is some kind of package that does this for you, but I did not find it yet.

[R] How to create a chromosome location map by locus ID
Sorry list, I guess I sent an html reply. Hi Sake: If you do not find an answer within the list, MapChart will probably do what you want (without the fancy chromosomal bands, though). You can find it at http://www.biometris.wur.nl/uk/Software/MapChart/ Hope this helps Sake escribi?:> Hi, > > I'm trying to make a chromosomal map in R by using the locus.

Of course I'm assuming that you are looking at human chromosomes ;-) If not then perhaps the UCSC Genome Browser may be of use as it has a large number genomes you can browse (see http://genome.ucsc.edu/cgi-bin/hgGateway ). If you really want to do this in R You might get some mileage out of the lodplot package which can draw ideograms (which is what a schematic of a choromsome with bandings from different stainings is called), although the dataset available for it is again for human chromosomes (see http://cran.r-project.org/web/packages/lodplot/index.html ). Perhaps worth checking out the Genetics Task View too thats linked from CRAN.
