Hi there,


I use plot(type="o") to draw the line. And I need put some legend to this
line. But how can I let the legend to display the line type in the graph
generated from type="o"? I can only find the lty in the legend. But I tried
several times and still failed.

Also, if I use abline(h=0.08) to draw a horizontal line and I also want to
show 0.08 in the y-axis, how can I do it?

Many thanks,


Yi
