IPA_baselineDeveloper: Develop a baseline for the chromatogram using local minima

In IDSL.IPA: Intrinsic Peak Analysis (IPA) for HRMS Data

Develop a baseline for the chromatogram using local minima

Description

This function generates a vector of baselines for the chromatogram using local minima. It also is capable of excluding outlier local minima to generate a realistic baseline including true baseline regions. This baseline may represent the local noise levels for the chromatogram.

Usage

IPA_baselineDeveloper(segment, int)

Arguments

segment	a matrix or a vecotr of adjusted scan number of local minima w/ or w/o redundant local minima. Adjusted scan numbers are the scan numbers but adjusted to start at 1.
int	a vector of intensities of the chromatogram.

Value

A vector of baselines in the same size of the "int" vector.

Examples

data(segment)
data(chromatogramMatrix)
int <- chromatogramMatrix$smoothChromatogram
IPA_baselineDeveloper(segment, int)
