nmr_baseline_removal {AlpsNMR} | R Documentation

## Baseline Removal NMR

### Description

Removes the baseline on an nmr_dataset_1D object, using baseline::baseline.als.

### Usage

    nmr_baseline_removal(nmr_dataset, lambda = 6, p = 0.05, maxit = 20)

### Arguments

`nmr_dataset` | An nmr_dataset_1D.
`lambda` | 2nd derivative constraint
`p` | Weighting of positive residuals
`maxit` | Maximum number of iterations

### Value

The same nmr_dataset_1D object after baseline removal.
