I have an expression matrix confined to the genes I wish to plot e.g. sample1 sample2 ... gene 1 gene 2 ... This may be a simple question, but is there a single command to do gene expression plots across all the samples? At the moment I am doing plot(expression[1,]) lines(expression[2,]) lines(expression[3,]) ... Is there a simpler way?

perhaps matplot() is what you are looking for. Note you might have to t() your matrix.
