How to plot a column of columns in R?

Question

Does anyone know how to use R to plot a histogram with columns stacked on more than 1 variable? Like the "stacked column" column in excel.

Thanks!

Answer 1

I assume that you really need a histogram, not a histogram. In this case, both barplotfrom standard graphics or barchartfrom the grid package, both will do this. Or use ggplot as shown in this example or here

Answer 2

For example:

ht1=c(0.3,0.7)
ht2=c(0.4,0.6)
barplot(cbind(ht1,ht2))

Answer 3

barplot.xts xtsExtra.
