[R] Axes of a histogram

[Rotkiv, Rehceb]

Hello everyone,

I would be glad if you could help out an R-beginner here... I have a
vector of categorial data like this

> v <- c(1, 1, 2, 2, 2, 3, 3, 4, 4, 4)

When I do

> hist(v)

I get the x-axis of the histogram with floating point labels: 1.0, 1.5,
2.0, etc. Is it possible to tell R that the data consists of categories,
i.e. that I only want the category names (1, 2, 3, 4) on my x-axis?

Thanks in advance,
Rehceb Rotkiv
