Hi You can use e.g. plot - points construction
plot(Day, gene1) points(Day, gene2, col=2) see ?points ?lines You also need to set appropriate y range by ylim argument to first plot. And if you used search facility in CRAN and asked it multiple plots on same x axis you would have got many other posibilities for your question.
