Spectral binning of intensity values stored in a Matrix object, converted from matter.

Spectral binning of intensity values stored in a Matrix object, converted from matter.

Usage

spectral_binning(
  matrix,
  ref,
  index,
  method = c("sum", "mean", "max", "min"),
  tolerance
)

Arguments

matrix

matter matrix object containing the intensity values to be binned.

ref

A vector of reference mass-to-charge (m/z) values for binning. If left unspecified, mass range will be used to generate reference peaks.

index

Character string specifying the column name for the m/z values (default = "mz").

method

A character vector specifying the binning method. Options include "sum", "mean", "max", "min". If not specified default method used is "sum".

tolerance

Numeric value specifying the tolerance for m/z matching (default = NA).

Value

Matrix object containing the binned intensity values matching the provided reference list.
