Hello,
There are several ways of doing this, perhaps the easiest is with ?matplot.
You should provide some data example, like the posting guide says. Since
you haven't, I've made up some.
y <- replicate(3, cumsum(rnorm(10)))
x <- matrix(c(1:10, y), ncol = 4)
matplot(x[, 1], x[, -1], type = "l")
Hope this helps,

Hello,
I'm very new to R, and have managed to plot xy graphs, but can't seem to
plot a matrix properly.
The first column is my time points, and the following columns 2-4 are the
replicates of my experiment.
I've tried using row.names=1 to make the first column the value for that row
(whereas before I had 1-31 sequence) and then my 1st column) but I can't
work out how to tell it that column 1 of my dataset is the xvalue for the
data in that row?
It's probably really simple, but I can't seem to figure it out!
Many thanks, any help appreciated!
Laura
