I have a matrix gene=array(rnorm(180), dim=c(18,10)) and a vector time=c(0, 0.5,2,4,6,8,12,24,48,72).
So i can get a plot with plot(time,gene[1,],type="b",col="green") for the first row.So how can i get all the 18 rows in the same plot VS. the same vector time=c(0,0.5,2,4,6,8,12,24,48,72). Any suggestions.Thanks !
