Hi Einat As Mehmet suggested, you can try plotGrandlinear in ggbio. an example codes in the manual are here http://tengfei.github.com/ggbio/docs/man/plotGrandLinear.html how to install http://www.bioconductor.org/packages/2.11/bioc/html/ggbio.html
But one thing is confusing(Maybe I don't get it right what you want), in Manhattan plot, the x-axis shows chromosome names like in those example, even though you have a short list with only 200 SNPs, if you hope to show gene names as x-axis, that's going to be tricky 1. 200(suppose each snp fall in different genes) x-axis labels in a row is hard or imporssible to read in the plot. 2. it's spread over multiple chromosomes, even if you really want to labels them with gene names, it's tricky to do in gglot2 level. IMHO, as a Manhattan overview, you don't have to show all the details like gene names, just to check general distribution and outliers. I guess what you want is probably a gene-list view like in IGV? http://www.broadinstitute.org/igv/gene_list_view suppose your 200 SNPs falls only to a few genes, let's say 10 genes. you may want something like each gene take one facet or panel in a row/grid of plots, would you mind to explain your case? or maybe you can shoot me personal email for collaboration on your case, because complex gene-slit views are not fully supported in ggbio yet.
