Find closest matches between numeric vectors

find_closest_match_dbl_2() identifies the closest matches between two numeric vectors.

Matches are determined by calculating the absolute differences between reference and target values. A user-defined tolerance sets the maximum acceptable difference for a match. The closest match is the pair with the smallest absolute difference that falls within the specified tolerance.

Usage

find_closest_match_dbl_2(x, y, x_ref, y_ref, tol = 0.05)

Arguments

x

A numeric vector.

y

A numeric vector.

x_ref

A numeric vector with reference values for x.

y_ref

A numeric vector with reference values for y.

tol

(Optional) A numeric value that sets the maximum acceptable difference for a match (Default: 0.05).

Value

If any value was found, returns the index of the closest match in x_ref/y_ref. Else, returns NA.
