Another possibility for visual display of several kinds of data is RCytoscape, for which an example can be seen here:
http://rcytoscape.systemsbiology.net/versions/current/gallery/TCGA/subnet.TCGA.02.0014.png This portrays 1) gene expression (green: under-expression; red: over-expression) 2) copy number (blue: high, black: low) 3) gene type (node shape: hexagons are kinases, arrows are ligands, diamonds are receptors, circles for everything else) 4) mutation status (not SNPs, but non-synonymous amino acid substitutions) 5) in the context of gene relationships, from KEGG A vignette for a larger version of this network is nearly complete. The Cytoscape network map is created from data and R code. - Paul On Apr 23, 2012, at 5:15 AM, Steve Lianoglou wrote: > Hi, > > On Mon, Apr 23, 2012 at 7:33 AM, Ekta Jain <ekta_j...@jubilantbiosys.com> > wrote: >> Hello, >> Can anyone please suggest any packages in R that can be used to overlay gene >> expression data on SNP (affymetrix) copy number ? > > I guess you mean visually?
