Hi.

I have two vectors of gene expression for each of
several days. I want to plot both vectors on the same
plot for a visual representation of up versus down
regulation. I've tried using add=T but that doesn't
work. 

eg
Any help would be appreciated.

Try 

plot(Day, gene1)
lines(Day, gene2)


see 

?lines
 
for more details.

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.
