[R] Gap between axis and bars in barplot()

[michael watson (IAH-C)]

Hi

Windows XP, R 2.0.1.

I am drawing a very large barplot using jpeg() - setting the width to
10,000 as there are over 5000 bars.

This all works fine and I get exactly what I want - except there is a
huge bit of white space between the Y-axis and the first bar - so much
in fact that I have to scroll two screens from the Y-axis before I see
the first bar.  After that the bars are evenly spaced and close
together.

Any ideas what is going on here?

Thanks in advance

Mick
