Method returning the range of step sizes in an object; i.e., the Range of
differences between successive sorted values. In particular the wavelength
step sizes [\(nm\)] of objects of class generic_spct
or derived (or
the step sizes of values in a numeric
vector).
Usage
wl_stepsize(x, ...)
stepsize(x, ...)
# S3 method for default
stepsize(x, ...)
# S3 method for numeric
stepsize(x, ...)
# S3 method for generic_spct
stepsize(x, ...)
# S3 method for generic_mspct
stepsize(x, ..., idx = "spct.idx")
Arguments
- x
an R object
- ...
not used in current version
- idx
character Name of the column with the names of the members of the collection of spectra.
