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")
Value
A numeric vector of length 2 with min and maximum stepsize values.
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.
Methods (by class)
stepsize(default): Default function usable on numeric vectors.
stepsize(numeric): Method for numeric vectors.
stepsize(generic_spct): Method for "generic_spct" objects.
stepsize(generic_mspct): Method for "generic_mspct" objects.
