resample.spectrum: Resample a spectrum to a given wavelength vector
In oczoske/slacR: R-package to measure v and sigma from VIMOS IFU cubes

Description Usage Arguments Value Warning Author(s) See Also

The function is basically a wrapper to approx. It takes a spectrum that is resampled to a wavelength vector given as the second argument.

1	resample.spectrum(input, target)

`input`	an object of class `spectrum` that is to be resampled
`target`	either an object of class `spectrum` (in which case only component `lambda` is used) or a numeric vector containing wavelength at which the spectrum is to be sampled.

An object of class spectrum. Most components are straight copies from input, except

`lambda`	this is the wavelength vector `target` (or its `lambda` component)
`value, contdiv, contsub`	the interpolation of `input$lambda` and (if present) `input$contsub` and `contdiv` onto `lambda`
`noise`	Since the function does not deal with the `noise` component of `input`, this is set to `NULL`

Note that "resampling" actually means "interpolating". I have not written a proper resampling code yet. Also, the function does not deal with the noise vector associated with the input spectrum.
