[R] R graphics: Add labels to stacked bar chart

[Jens Oldeland]

Hi,

I am looking for a way to add labels, i.e. absolute values, into a 
stacked bar chart using the basic plot functions of R. The labels should 
be inside the stacked bars.

For example,

###  I have this dataset

height = cbind(x = c(465, 91) / 465 * 100,
                       y = c(840, 200) / 840 * 100,
                       z = c(37, 17) / 37 * 100)

### and use this plot
barplot(height,
        beside = FALSE,
        horiz=T,
        col = c(2, 3)
        )
     
how can I put the values from height within the respective stacked bars?

Thank you!
