[R] lines and legend

[Sundar Dorai-Raj]

Hi Anna,
What I often do before calling legend is reset the user-coordinates to 
the unit square. As in:

plot(x = 1:100, y = 1:100, col = "red")
par(usr = c(0, 1, 0, 1))
# now place legend in upper left hand corner
legend(x = 0.02, y = 0.98,
       legend = "test", col = "red", pch = 1)

Hope this is helpful,

Sundar
