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!
