R help - Jan 2000 - barplot axes

Hi everyone

I seem to be having a problem with the y axis in barplot.

The default y axis produced by barplot begins at 0 and extends up to the
maximum value of y. I would like it to extend a little further so that I
can add error bars and a legend to my plot. 

Setting ylim=c(0,..) has the strange effect of removing the 0 from the
axis and changing the interval between tick marks without necessarily
making the axis extend to the upper value specified. It seems it is not
possible to make the axis start at 0 when using ylim.

I see that it's not yet possible to set yaxs = "s" or
"e", which I thought
might help. Am I missing something? 

(I'm using R v 0.90)

Karen

A bugfix... axes with yaxs="i" doesn't include the endpoints. They
do
in S+ and really should do it in R too. The easiest workaround is
along the lines of

  barplot(1:10,ylim=c(-.01,14.01))

(ylim does actually work for setting the plot area. Try adding a box()
to see it).
