ppm: Return the ppm scale of an MRS dataset or fit result.

In neuroconductor-releases/spant: MR Spectroscopy Analysis Tools

Description

Return the ppm scale of an MRS dataset or fit result.

Usage

ppm(x, ft = NULL, ref = NULL, fs = NULL, N = NULL)

## S3 method for class 'mrs_data'
ppm(x, ft = NULL, ref = NULL, fs = NULL, N = NULL)

## S3 method for class 'fit_result'
ppm(x, ft = NULL, ref = NULL, fs = NULL, N = NULL)

Arguments

x	MRS dataset of fit result.
ft	transmitter frequency in Hz, does not apply when the object is a fit result.
ref	reference value for ppm scale, does not apply when the object is a fit result.
fs	sampling frequency in Hz, does not apply when the object is a fit result.
N	number of data points in the spectral dimension, does not apply when the object is a fit result.

Value

ppm scale.
