Performs baseline correction on infrared spectra using a polynomial

Source: R/ir_bc.R
ir_bc_polynomial.Rd

ir_bc_polynomial performs baseline correction for infrared spectra using a polynomial. ir_bc_polynomial is an extended wrapper function for ChemoSpec::baselineSpectra().

Usage

ir_bc_polynomial(x, degree = 2, return_bl = FALSE, ...)

Arguments

x

An object of class ir.

degree

An integer value representing the degree of the polynomial used for baseline correction.

return_bl

A logical value indicating if for each spectrum the baseline should be returned instead of the corrected intensity values (return_bl = TRUE) or not (return_bl = FALSE).

...

Ignored.

Value

An object of class ir with the baseline corrected spectra if returnbl = FALSE or the baselines if returnbl = TRUE.

if(! requireNamespace("ChemoSpec", quietly = TRUE)) {
  x2 <-
     ir::ir_sample_data |>
     ir::ir_bc_polynomial(degree = 2, return_bl = FALSE)
}
