Stepsize

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, ...)

# Default S3 method
stepsize(x, ...)

# S3 method for class 'numeric'
stepsize(x, ...)

# S3 method for class 'generic_spct'
stepsize(x, ...)

# S3 method for class 'generic_mspct'
stepsize(x, ..., idx = "spct.idx")

Arguments

x

an R object

...

idx

character Name of the column with the names of the members of the collection of spectra.

Value

A numeric vector of length 2 with min and maximum stepsize values.
