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
