# .bincode

##### Bin a Numeric Vector

Bin a numeric vector and return integer codes for the binning.

- Keywords
- category

##### Usage

`.bincode(x, breaks, right = TRUE, include.lowest = FALSE)`

##### Arguments

- x
a numeric vector which is to be converted to integer codes by binning.

- breaks
a numeric vector of two or more cut points, sorted in increasing order.

- right
logical, indicating if the intervals should be closed on the right (and open on the left) or vice versa.

- include.lowest
logical, indicating if an ‘x[i]’ equal to the lowest (or highest, for

`right = FALSE`

) ‘breaks’ value should be included in the first (or last) bin.

##### Details

This is a ‘barebones’ version of ```
cut.default(labels =
FALSE)
```

intended for use in other functions which have checked the
arguments passed. (Note the different order of the arguments they have
in common.)

Unlike `cut`

, the `breaks`

do not need to be unique.
An input can only fall into a zero-length interval if it is closed
at both ends, so only if `include.lowest = TRUE`

and it is the
first (or last for `right = FALSE`

) interval.

##### Value

An integer vector of the same length as `x`

indicating which bin
each element falls into (the leftmost bin being bin `1`

).
`NaN`

and `NA`

elements of `x`

are mapped to
`NA`

codes, as are values outside range of `breaks`

.

##### Examples

`library(base)`

```
# NOT RUN {
## An example with non-unique breaks:
x <- c(0, 0.01, 0.5, 0.99, 1)
b <- c(0, 0, 1, 1)
.bincode(x, b, TRUE)
.bincode(x, b, FALSE)
.bincode(x, b, TRUE, TRUE)
.bincode(x, b, FALSE, TRUE)
# }
```
