hsvd_filt(mrs_data, xlim = c(-30, 30), comps = 40, irlba = TRUE, max_damp = 10)| mrs_data | MRS data to be filtered. |
|---|---|
| xlim | frequency range in Hz to filter. |
| comps | number of Lorentzian components to use for modelling. |
| irlba | option to use irlba SVD (logical). |
| max_damp | maximum allowable damping factor. |
