\title{Interpolates intensity values of infrared spectra in an \code{ir} object for new wavenumber values}
\usage{
ir_interpolate(x, start = NULL, dw = 1)
}
\arguments{
\item{x}{An object of class \code{\link[=ir_new_ir]{ir}}.}

\item{start}{A numerical value indicating the start wavenumber value relative
to which new wavenumber values will be interpolated. The value is not allowed
to be < \code{floor(firstvalue) - 2}, whereby \code{firstvalue} is the first
wavenumber value within \code{x}. If \code{start = NULL},
\code{floor(firstvalue)} will be used as first wavenumber value.}

\item{dw}{A numerical value representing the desired wavenumber value
difference between adjacent values.}
}
\value{
An object of class \code{ir} containing the interpolated spectra. Any
\code{NA} values resulting from interpolation will be automatically dropped.
}
\description{
\code{ir_interpolate} interpolates intensity values for infrared spectra for
new wavenumber values.
