Hello Newb here, I have a list of ratios for a set of genes and I would like to look at their expression profile using a heat map. The data for 1 gene looks like this: tissue1 tissue2 tissue3 tissue4 tissue5 tissue5 gene 1 -0.29 -0.64 -0.6 -0.62 -0.27 NA Is there a way to do this using Bioconductor? Also, I am wondering if anyone can recommend a book or site for learning Bioconductor. I am primarily concerned with analying exon arrays but am intrigued by the other gadgets BioC seems to have? TIA [[alternative HTML version deleted]]
