Hi

I have som problems with a barplot. It can be created easily in Excel but I cant manage to get it right in R.

For example:
MyData <-
matrix(c(1,2,-1,-1,0,-2,-2,1,1,1,-2,3),ncol=3,dimnames=list(LETTERS[1:4],seq(3)))

I want the barplot to stack the positive and negative values separatly so that positive values are stacked over 0 and negative is stacked under 0.

I have added a jpg of the graph in excel http://www.nabble.com/file/p15542914/Excel.jpg Excel.jpg

Regards Tom
