[R] barplot

[alexander.schnee@tuebingen.mpg.de]

Hi,
a couple of simple graphics questions:
 
1. I have a little function that makes bar plots. Now I would like to 
limit the Y-axis outside this
function (that means after calling the barplot() command) depending on
the data to be plotted .
Does anyone know how to do this ???
 
2. When using barplot() and limiting the yAxis, R draws the bars below
the x-axis. How can I avoid this problem ??
 
thanks for answers
alex
