Let me guess, and sorry if I am wrong:

You want to plot the point at   
 x = -15
 y = 57.5

but you told R to plot it at:
 x = 1, 2
 y = -15, 57.5

So what you should try is:
 points(-15.0, 57.5)

Maybe there is no need to do this, but if so, just put it on your web
page and tell us the location (reducing bandwidth).
