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

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 <- c(0,0,0,1,1,2)
hist(a, freq=FALSE)

I want to see a histogram with the following relative frequencies:

.5 for 0 to 1,

.33 for 1 to 2,

and .166 for 2 to 3.

Solution

  • you can try using the histogram() function in lattice

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

    defaults to percent.
