[R] matlab style plotting in R

[Stefan Grosse]

There are many ways if I understood what you indend to do:

example data:
toplot<-data.frame(x=c(1:5,1:5),y=rnorm(10),sbs=c(rep("a",5),rep("b",5)))

1st with plot itself:

plot(y~x,data=toplot,type="n")
lines(y~x,data=subset(toplot,sbs=="a"),type="b",pch=4,col="blue")
lines(y~x,data=subset(toplot,sbs=="b"),type="b",pch=2,col="red")


2nd with xyplot out of the lattice package:
library(lattice)
xyplot(y~x,groups=sbs,data=toplot,pch=c(2,4),main="Title")

to see some variants. My advice is to look at a good documentation at
the homepage (contributed documentation) or book ...
