Crop frequency series to a given range
Usage
cutoff_to(fs, ref, frange = NULL)
Arguments
- fs
A `fs` object (frequency series).
- ref
A vector with elements: `c(min, max)`, indicating index range.
- frange
A vector of frequency range. `frange[1]` can be larger than `ref[1]` and `frange[2]` can be smaller than `ref[2]`, so as to consider the specific frequency range.
Value
A cropped `fs` object with preserved attributes.
