ir (version 0.2.1)

ir_divide: Divide infrared spectra or divide infrared spectra by a numeric value

Description

ir_divide takes two objects of class ir, x and y, and divides their intensity values, or it takes one object of class ir, x, and one numeric value, y, and divides all intensity values in x by y.

Usage

ir_divide(x, y)

Value

x where for each spectrum intensity values are divided by the respective intensity values in y (if y is an object of class ir), or where all intensity values are divided by y if y is a numeric value.

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.

Examples

# division with y as ir object
x1 <-
  ir::ir_divide(ir::ir_sample_data, ir::ir_sample_data)
x1 <-
  ir::ir_divide(ir::ir_sample_data, ir::ir_sample_data[1, ])

# division with y being a numeric value
x2 <-
  ir::ir_divide(ir::ir_sample_data, y = 20)
