[R] barplot

[Lorenz Gygax]

Dear all,

I am currently trying to draw some barplots. I have positive and negative
values in my columns and I would like the positive values to be stacked on
top of each other in the positive and the negative values stacked in the
negative direction. Barplot just seems to add one value to the next
consecutively.

Do you see an other way to achieve what I want except rewriting the code
of barplot, such that positive and negative values are treated seperately?

Thanks! Regards, Lorenz
