ir_interpolate

<code>ir_interpolate</code> interpolates intensity values for infrared spectra for
new wavenumber values.

Functions to import and handle infrared spectra (import from '.csv' and
Thermo Galactic's '.spc', baseline correction, binning, clipping,
interpolating, smoothing, averaging, adding, subtracting, dividing,
multiplying, atmospheric correction, 'tidyverse' methods, plotting).

ir_interpolate function

<dl><dt>x</dt>
<dd>An object of class <code>ir</code>.</dd>
<dt>start</dt>
<dd>A numerical value indicating the start wavenumber value relative
to which new wavenumber values will be interpolated. The value is not allowed
to be &lt; <code>floor(firstvalue) - 2</code>, whereby <code>firstvalue</code> is the first
wavenumber value within <code>x</code>. If <code>start = NULL</code>,
<code>floor(firstvalue)</code> will be used as first wavenumber value.</dd>
<dt>dw</dt>
<dd>A numerical value representing the desired wavenumber value
difference between adjacent values.</dd>
<dt>return_ir_flat</dt>
<dd>Logical value. If <code>TRUE</code>, the spectra are returned as
<code>ir_flat</code> object.</dd></dl>
