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:
>legend(80,1150, c("Simulation", "Observation", lty=1:2, col=2:3)

You've got mismatched parentheses here, with two ( and only one ).

I suspect you added one at the end, making r look at lty= and col = as part of the legend text.

You want

legend(80,1150, c("Simulation", "Observation"), lty=1:2, col=2:3)
