R: Tabulation for Vectors

## Tabulation for Vectors

### Description

`tabulate` takes the integer-valued vector `bin` and counts the number of times each integer occurs in it.

### Usage

    tabulate(bin, nbins = max(1, bin))

### Arguments

`bin` | a numeric vector (of positive integers), or a factor.
`nbins` | the number of bins to be used.

### Details

`tabulate` is used as the basis of 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 to the nearest integer.

### Value

An integer vector (without names). There is a bin for each of the values `1, ..., nbins`; values outside that range are (silently) ignored.

### See Also

`table`, `factor`.

### Examples

    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]))
