Scale mrs_data to a spectral region.

Usage

scale_spec(
  mrs_data,
  xlim = NULL,
  operator = "sum",
  freq_scale = "ppm",
  mode = "re",
  mean_dyns = NULL,
  ret_scale_factor = FALSE
)

mrs_data: MRS data.
xlim: spectral range to be integrated (defaults to full range).
operator: can be "sum" (default), "mean", "l2", "max", "min" or "max-min".
freq_scale: units of xlim, can be : "ppm", "Hz" or "points".
mode: spectral mode, can be : "re", "im", "mod" or "cplx".
mean_dyns: mean the dynamic scans before applying the operator. The same scaling value will be applied to each individual dynamic.
ret_scale_factor: option to return the scaling factor in addition to the scaled data.

normalised data.
