The numbers on the corner of their bar in the histogram, how can I get them centered under the bar?

I am plotting a histogram with the hist standard function with this example dataset:

v= c(0L, 0L, 0L, 1L,1L,1L,2L, 2L, 2L,4L, 4L, 4L)
hist(v, main='example', xlab='example', ylab='example', breaks=5)

      

        
        
        
      

    

The problem I am facing is that the image with histogram looks like this:

| ___
||   |
||   |___     ___ 
||   |   |   |   |
||___|___|___|___|
 0   1   2   3   4

      

        
        
        
      

    

So, because 0 starts at a corner, the combinations of 0 and 1 are merged, and panel 2 and 4 looks like it belongs to 1 and 2, 3 and 4. What I want to have is

| 
|   
| ___ ___ ___     ___
||   |   |   |   |   |
||___|___|___|___|___|
   0   1   2   3   4

      

        
        
        
      

    

I tried to change the breaks, but that doesn't solve the problem of the numbers on the corner. How can I get the numbers to be centered under the bars?
