[R] plot question

[Joerg Maeder]

Hello Myriam,

use lines for the second plot
...
plot(x,testone,.....)
lines(z,testtwo,lty=4,col='red')
xlabel.....
....

or add NA's two testtwo and make a matrix out oft testone and testtwo
and use matplot
d <- cbind(testone,c(testtwo,rep(NA,length(testone)-length(testtwo))))
matplot(d,typ='l')
