Hi,
I would like to find an "easy" way to get a graphical representation of a set of SNP markers along chromosomes? (I have their names, chromosome number they belong to and their position, in bp, on the chromosome) Is there any dedicated R package(s) or software I can use to produce such figure? I was unable to find what I'm looking for...
Thanks very much, Cheers, Christopher

You might look at Genome Graphs tool from UCSC: http://genome.ucsc.edu/cgi-bin/hgGenome
They don't have any sample images, but we did a post on it once way back--it's not a great example but you can get a sense of what it would do if there was data available: http://blog.openhelix.eu/?p=670
They used to have sample data sets to look at but had to retract them in the privacy controversy over the public GWAS data.
This might give you some pointers on how to go about it

I'm also interested in knowing how to do something similar. I'd like to be able to create a set of chromosomes (using arbitrary lengths (non human organism)) and visualize a set of markers on them given their position.
Have you tried LocusZoom, snp.plotter or SNAP? See this discussion.
