I was trying to calculate equal quantile cuts for a vector by using cut2 from Hmisc.

```
library(Hmisc)
c <- c(-4.18304,-3.18343,-2.93237,-2.82836,-2.13478,-2.01892,-1.88773,
-1.83124,-1.74953,-1.74858,-0.63265,-0.59626,-0.5681)
cut2(c, g=3, onlycuts=TRUE)
[1] -4.18304 -2.01892 -1.74858 -0.56810
```

But I was expecting the following result (33%, 33%, 33%):

```
[1] -4.18304 -2.13478 -1.74858 -0.56810
```

Should I still use cut2 or try something different? How can I make it work? Thanks for your advice.

## Best Solution

You are seeing the cutpoints, but you want the tabular counts, and you want them as fractions of the total, so do this instead:

(Obviously you cannot expect cut2 to create an exact split when the count of elements was not evenly divisible by 3.)
