I'm new with R. I want to plot 3 lines in one graph. This is my data:

print(x)
     V1       V2       V3      V41 -4800 25195.73 7415.219 7264.282
-2800 15195.73 5415.219 7264.28

I tried using matplot, but I cannot get exactly what I want. This is what I
get, and this is my code:

matplot(x[,1],x[,-1],type='b', xlab = "epsilon_h",
        ylab = "Value2", xlim= range(-4500,-100),
        col = c("blue","green","red"), pch=1:3)
ex12 <- expression(V(h == 40),
                   V(h==20),
                   V(h==0))
legend("topright", ex12, col = c("blue","green","red"), pch=1:3)

I would like to make the lines extend so I can see the intersections.


The other, fancier and better looking, option that i found is ggplot2. But
for what I understand from the
example<http://wiki.stdout.org/rcookbook/Graphs/Scatterplots%20(ggplot2)/>I
would need to reshape my data to something like this

     id       x       y      1     1     -4800   25195.73
2     1     -2800   15195.733     2     -4800   7415.2194     2
-2800   5415.2195     3     -4800   7264.286     3     -2800   7264.28

Thanks a lot for the help!
