mapToIntervals.numeric

Maps values to intervals

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

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

`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.

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