R help - Dec 2006 - barplot - how to force vertical axis to cover entire plot area

I'm using barplot with the following call:
  
barplot(stat_data[[5]][,],axes=TRUE,axisnames=TRUE,axis.lty=1,xlab=xlab,ylab=ylab,beside=TRUE,las=1,font.lab=2,font.axis=1,legend.text=TRUE)

On some data, the vertical axis does not cover the
whole plot area and the last tick mark is smaller than
the maximum value.

I tried setting the ylim values but even with that,
some plots are still not OK, it just shrinks the
length of the bars.

Attached is a png example of the problem.  I hope it
gets through.

Thanks,
Etienne

The example is not reproducible and poorly formatted. Please read the 
posting guide.

R tries to make the plot pretty, i.e. stop with some tick mark like 200, 
but not e.g. 242.

Perhaps you want to make a box() around the plot?

Hi, Etienne,
 
I've seen this while working with barplot and never been able to understand
the general rule, but by setting ylim high enough, I've always been able to
draw a y axis covering the biggest values.
 
Could you send a data subset to reproduce the issue? Thanks.
 
Best,
 
Ricardo
