\title{Arithmetic operations for \code{ir} objects}
\usage{
\method{Ops}{ir}(e1, e2)
}
\arguments{
\item{e1}{An object of class \code{ir}.}

\item{e2}{An object of class \code{ir} or a numeric value.}
}
\value{
\code{e1} with intensity values of the spectra added to/subtracted
with/multiplied with/divided by those in \code{e2}:
\itemize{
\item If \code{e2} is a numeric value, all intensity values in the spectra of \code{e1} are
added/subtracted/multiplied/divided by \code{e2}.
\item If \code{e2} is an \code{ir} object with one row, it is replicated (see \link{rep.ir}) so
that the row numbers match to those of \code{e1} and intensity values are
added/subtracted/multiplied/divided row-wise.
\item If \code{e2} is an \code{ir} object with the same number of rows as \code{e1}, intensity
values are added/subtracted/multiplied/divided row-wise.

\examples{
## addition
ir::ir_sample_data + ir::ir_sample_data
ir::ir_sample_data + 2
ir::ir_sample_data +
   seq(from = 0, to = 2, length.out = nrow(ir::ir_sample_data))

## subtraction
ir::ir_sample_data - ir::ir_sample_data
ir::ir_sample_data - 2
ir::ir_sample_data -
   seq(from = 0, to = 2, length.out = nrow(ir::ir_sample_data))

## multiplication
ir::ir_sample_data * ir::ir_sample_data
ir::ir_sample_data * 2
ir::ir_sample_data *
   seq(from = 0, to = 2, length.out = nrow(ir::ir_sample_data))

## division
ir::ir_sample_data / ir::ir_sample_data
ir::ir_sample_data / 2
ir::ir_sample_data /
   seq(from = 0.1, to = 2, length.out = nrow(ir::ir_sample_data))
