ir_add {ir}

Add infrared spectra

Description

ir_add takes two objects of class ir, x and y, and adds the intensity values of spectra in matching rows from y to that of x.

Usage

ir_add(x, y)

Arguments

x

An object of class ir.

y

An object of class ir or a numeic value. If y is an object of class ir, it must have the same number of rows as x and the same x axis values (e.g. wavenumber values) in each matching spectrum as in x.

Value

x where for each spectrum the respective intensity values in y are added.

Examples

x1 <-
  ir::ir_add(ir::ir_sample_data, ir::ir_sample_data)
x1 <-
  ir::ir_add(ir::ir_sample_data, ir::ir_sample_data[1, ])
