How to plot several graphs in a single 2-D figure?
Thanks, Iyue But here the data1 and data2 are not necessarily two vectors. Maybe they are results from some other functions, defined as a data structure. Like using norMix package, x <- norMix(mu=c(-1,0,1.5),sig2=c(.49,.36,.16),w=c(.4,.3,.3)); plot(x); %% x is not a vector, but a structure y <- norMix(mu=c(-2,0,2),sig2=c(.16,.36,.64),w=c(.4,.3,.3)); par(new=T); plot(y); The result graph is messed up and x,y dont have consistent axis label settings.

Fred, Try:
xrange<-range(c(data1[,1],data2[,1])) yrange<-range(c(data1[,2],data2[,2])) plot(data1, xlim=xrange, ylim=yrange, pch=1) points(data2, pch=2)

Hi, R-listers I tried to plot several graphs in a sigle x-y coordinate settings, like the following: |(y) s | ****** s | ***** s | sssssssssssssssssss |_______________________________(x) where "*" and "s" denote two diffrent plots. However, when I used plot(data1); % data1 is the data points of "*" par(new=T); plot(data2); % data2 is the data points of "s" I found that the x and y labels are messed up, since different graphs use diffrent unit length on the x-axis and y-axis. So is there someway to avoid this problem? Or is there some other function plottting multiple plots in one x-y axis setting? Thanks for your point and help. Fred
