This works for me:
> plot(1:10, 1:10)
> legend("topleft", c("Simulation", "Observation"), lty=1:2, col=2:3)

Try that; if it does work, then we need more information about
exactly what you're doing, because there's a problem not contained
in just that single line of code (which has a problem of its own!).

Instead, under the variable names, the numbers 1, 2, 2, 3 are displayed in a column (with '2' repeated twice). This is the code I'm using:
