Dear all,
I'm attempting to insert a legend into a line graph. I've sorted out the
positioning, but I'm unable to display the sample line and associated colour
to go within the legend box. 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)
How do I go about displaying a red solid line next to 'Simulation' and a
green dashed line next to 'Observation' (and if necessary, remove the
numbers that are currently displayed)?
Many thanks for any help offered,
Steve

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) HTH Peter Peter L.

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!).

Dear Steve,
Try this:
x<-rnorm(100)
y<-rnorm(100) + 2*x
plot(x,y)
legend('topleft', c("Simulation", "Observation"),
lty=1:2, col=2:3)
abline(x,y,col=3,lty=2)
(you forgot a ")" in your code :( )
HTH,
Jorge

your code is missing a closing bracket for the text labels,
legend(1,4, c("Simulation", "Observation"), lty=1:2,
col=2:3)
