R help - Sep 2009 - Newbie Question About Setting Plot Axis Limits

Using the following: plot(c(1,1), ylim=c(0, 15), xlim=c(0, 13))

However, it produces the following:

This is not what I expected because I would have expected the origin to be (0,
0), but on the plot it looks a little different on the plot.

The y axis also appears to extend a little beyond 15.  Is there some way to have
the plot command respect the requested ylim and xlim settings?

Thanks again for any insight.

This is not a complete answer, but try the following in order

plot(c(1,1), ylim=c(0, 15), xlim=c(0, 13), axes = FALSE)
axis(1)
axis(2)
box()

If you want lines, use abline.  Hacking something together can be done
with these commands.

  par(xaxs="i",yaxs="i")
  plot(c(1,1), ylim=c(0, 15), xlim=c(0, 13))
