Question

How do you use hist() to plot relative frequencies in R?

If I do the following, I will get a density plot, but I want a relative frequency plot:

a &l         


        

Answer 1

you can try using the histogram() function in lattice

a <- c(0,0,0,1,1,2)
library(lattice)
histogram(a)

defaults to percent.
