Which Nearest

Description

Find values of one vector that are nearest to values in another vector.

Usage

which.nearest(x, y)

Arguments

x	vector of values to be compared against.
y	vector of values to examine relative to x. May be of length 1. @return For each value in y, returns index of value of x which is nearest to y in absolute value. In the case of ties, the function returns the first index of x. If nearest value is min(x) or max(x), a warning is issued. NAs and NaNs in x are ignored; NAs and NaNs in y are returned.
