R Documentation

A wrapper around base::findInterval() that allows decreasing values in the value of the vector within which we wish to place values of x.

Description

When vec is in ascending order we use base::findInterval(), but when vec is in descending order we implement an adaptation of the locate() function from Numerical Recipes for C http://apps.nrbook.com/c/index.html

Usage

find_interval(x, vec, rightmost.closed = FALSE, all.inside = FALSE)

Arguments

`x`	numeric values we wish to located within `vec`
`vec`	numeric vector of sorted values (ascending or descending order) within which we wish to find the placement of `x`
`rightmost.closed`	see findInterval
`all.inside`	see findInterval
