# tabulate

##### Tabulation for Vectors

`tabulate`

takes the integer-valued vector `bin`

and counts
the number of times each integer occurs in it.

- Keywords
- arith

##### Usage

`tabulate(bin, nbins = max(1, bin, na.rm = TRUE))`

##### Arguments

- bin
a numeric vector (of positive integers), or a factor. Long vectors are supported.

- nbins
the number of bins to be used.

##### Details

`tabulate`

is the workhorse for the `table`

function.

If `bin`

is a factor, its internal integer representation
is tabulated.

If the elements of `bin`

are numeric but not integers,
they are truncated by `as.integer`

.

##### Value

An integer valued `integer`

or `double`

vector
(without names). There is a bin for each of the values ```
1,
…, nbins
```

; values outside that range and `NA`

s are (silently)
ignored.

On 64-bit platforms `bin`

can have \(2^{31}\) or more
elements (i.e., `length(bin) > .Machine$integer.max`

), and hence
a count could exceed the maximum integer. For this reason, the return
value is of type double for such long `bin`

vectors.

##### Examples

`library(base)`

```
# NOT RUN {
tabulate(c(2,3,5))
tabulate(c(2,3,3,5), nbins = 10)
tabulate(c(-2,0,2,3,3,5)) # -2 and 0 are ignored
tabulate(c(-2,0,2,3,3,5), nbins = 3)
tabulate(factor(letters[1:10]))
# }
```
