In metabodecon: Deconvolution and Alignment of 1d NMR Spectra

Convert from unit A to unit B

Description

Converts positions/widths from unit A to unit B. If the direction of units A and B is reversed, the width's sign will be reversed as well. To keep widths strictly positive, wrap the result with abs().

Usage

convert_pos(xa, ya, yb)

convert_width(xa, ya, yb)

Arguments

xa	A numeric vector specifying widths/positions in unit A.
ya, yb	A numeric vector specifying the positions of at least two points in unit A / unit B.

Value

A numeric vector of values converted from unit A to unit B.
