R help - Jan 2005 - plot

Is it possible to make multiple plots i.e. to represent more than one
function on the same figure?

Thank you

It you want to superimpose the curves, for example:

t=seq(-5,5,.1)
plot(t,exp(-t*t),type='l')
lines(t,sin(t)*sin(t))


If you want to plot on separate plotting areas:

par(mfcol=c(1,2))
plot(t,exp(-t*t),type='l')
plot(t,sin(t)*sin(t),type='l')

hello,

I wonder whether there is a way to plot in R the following:

I have two arrays of dimension (200*1) say x1 and x2.
I would like to plot on the same graph x1[1:50,]*x2[1:50,] with pch=1  
                        

                                       x1[51:100,]*x2[51:100,] with pch=2
                                     x1[101:150,]*x2[101:150,] with pch=3
                                      x1[151:200,]*x2[151:200,] with pch=4
is it possible with the "plot" function? Or do I have to plot
4differents graphs?
THanks in advance.

try this:

x1 <- as.matrix(rnorm(200))
x2 <- as.matrix(rnorm(200))
###############
dim(x1) <- dim(x2) <- c(50,4)
matplot(x1,x2, pch=1:4, col=1)



Best,
Dimitris

You can specify pch in form of a vector (as long as x1) as in:

plot(1:10, pch=rep(1:2, each=5))
