Use abline?  ?axis explicitly tells you

      The axis line is drawn from the lowest to the highest value of
      'at', but will be clipped at the plot region.

Without any code (let alone a reproducible example) we can only guess at 
what you did.

A standard R scatter plot has an x-axis that does not extend to the ends, 
but it overlays a box().  If you only want the bottom line of the box, use 
abline or lines to plot it.
