In hiraksarkar/edgeR_fork: Empirical Analysis of Digital Gene Expression Data in R

Description

Find nearest element of a sorted reference vector and to each element of x.

Usage

nearestReftoX(x, reference, ...)

Arguments

x	numeric vector.
reference	numeric vector, sorted in increasing order.
...	other arguments as passed to findInterval.

Details

This function finds the element of a reference table (reference) that is closest to each element of an incoming vector (x).

The function is a simple wrapper for findInterval in the base package. It calls findInterval with vec equal to the mid-points between the reference values.

Value

Integer vector giving indices of elements of reference.
