I'd be grateful for any suggestions as to how I should go about this.
I think what you are doing wrong is misinterpreting what people mean when they say "line". They don't mean line of data, they mean line on the plot. Does this get you started? lat <- seq(-55:-50) simrun <- c(574.09, 247.23, 103.41, 86.99, 45.22, 55.93) obsrun <- c(491.95, 319.66, 237.82, 179.54, 105.30, 136.61) plot(simrun~lat,type = 'l') lines(obsrun~lat) Peter Peter L.
