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.
