GenomeGraphs uses the biomaRt package to perform live annotation queries to Ensembl and translates this to e.g. gene/transcript structures in viewports of the grid graphics package. This results in genomic information plotted together with your data. Another strength of GenomeGraphs is to plot different data types such as array CGH, gene expression, sequencing and other data, together in one plot using the same genome coordinate system. http://bioconductor.org/packages/2.4/bioc/html/GenomeGraphs.html Nandini Badarinarayan Gene expression dataset Graph plot R software image format
