IOanna,
If you are trying to distinguish between the type="b" and the type="o" in
the legend, there does not appear to be a way to do this with the legend()
function in base. I found a similar question posted on stackoverflow, and
they suggested a work around for something similar (but not quite the same).
http://stackoverflow.com/questions/18233236/how-to-get-lines-of-type-b-in-a-legend
Here's an example, using your data.
X1<-c(0,1,2,3,4)
Y1<-c(0,1,2,3,4)
Y2<-c(5,6,7,8,9)
Y3<-c(32,33,34,35,36)
plot(X1,Y3,pch=20, ylim=range(Y1, Y2, Y3))
lines(X1,Y1,lty=1,type='o')
lines(X1,Y2,lty=1,type='o', pch=21, bg="white")
lines(X1,Y3,lty=2)
legend("center", c("Y3", "Y2", "Y1"), lty=c(2, 1, 1), pch=c(20, 21, 1),
pt.bg=c(NULL, "white", NULL))
