Spectra-class {ASICS} | R Documentation

## Class Spectra

### Description

Objects of class Spectra contain a set of NMR spectra. It includes preprocessed spectra and can be created with the function `createSpectra`.

### Slots

`sample.name`

  Character vector of sample names.

`ppm.grid`

  Numeric vector of a unique grid (definition domain) for all spectra (in ppm).

`spectra`

  Numeric matrix with all spectra in columns. Columns must be in the same order as for `sample.name` and rows correspond to points of `ppm.grid`.

### Methods

Multiple methods can be applied on Spectra objects.

- As usual for S4 object, show and summary methods are available, see Object summary

- All slots have an accessor `get_slot name`, see Accessors

- Two objects can be combined or a subset can be extracted, see Combine and subset methods

- All spectra contained in an object can be represented in a plot, see Visualisation methods
