R: Maps values to intervals

mapToIntervals.numeric {R.utils} | R Documentation

## Maps values to intervals

### Description

Maps values to intervals by returning an index `vector` specifying the (first) interval that each value maps to, if any.

### Usage

    ## S3 method for class 'numeric'
    mapToIntervals(x, intervals, includeLower=TRUE, includeUpper=TRUE, ...)

### Arguments

`x` | A `numeric` `vector` of K values to be matched.
`intervals` | The N intervals to be matched against. If an Nx2 `numeric` `matrix`, the first column should be the lower bounds and the second column the upper bounds of each interval. If a `numeric` `vector` of length 2N, each consecutive pair should be the lower and upper bounds of an interval.
`includeLower, includeUpper` | If `TRUE`, the lower (upper) bound of each interval is included in the test, otherwise not.
`...` | Not used.

### Value

Returns an `integer` `vector` of length K. Values that do not map to any interval have return value `NA`.
