In several papers I have seen a plot which illustrates the value of
expression of several genes (usually in a cluster) over time. The y axis is
expression, the x axis is discrete time points, and each of the points for a
gene are connected by lines so one can easily see a time profile.

Is there a predefined function for this? If not, what plot parameters do I
use?

Thanks,
Mark
