restrict_range() restricts wavenumber ranges to user specified values.
Multiple ranges can be specified by inputting a series of max and min
values in order.
flatten_range() will flatten ranges of the spectra that should have no
peaks.
Multiple ranges can be specified by inputting the series of max and min
values in order.
Usage
restrict_range(x, ...)
# S3 method for default
restrict_range(x, ...)
# S3 method for OpenSpecy
restrict_range(x, min, max, make_rel = TRUE, ...)
flatten_range(x, ...)
# S3 method for default
flatten_range(x, ...)
# S3 method for OpenSpecy
flatten_range(x, min = 2200, max = 2400, make_rel = TRUE, ...)Arguments
- x
an
OpenSpecyobject.- min
a vector of minimum values for the range to be flattened.
- max
a vector of maximum values for the range to be flattened.
- make_rel
logical; should the output intensities be normalized to the range [0, 1] using
make_rel()function?- ...
additional arguments passed to subfunctions; currently not in use.
Value
An OpenSpecy object with the spectral intensities within specified
ranges restricted or flattened.

spectra = data.frame(intensity = rnorm(361)))
