In oczoske/slacR: R-package to measure v and sigma from VIMOS IFU cubes

The function makes sure that a mask is a vector along a given wavelength vector, converting input such as a file name or a data.frame.

1	convert.mask(x, mask)

`x`	a wavelength vector or an object of class `spectrum`
`mask`	Normally the name of a file or of a `data.frame` with components `x1` and `x2` giving the left and right limits of the wavelength regions to be masked. Can also be a logical scalar or vector, but then the function does not do much.

a logical vector along the wavelength vector x or x$lambda, with TRUE for pixels outside the wavelength regions given by mask

mask.df <- data.frame(x1=c(4000, 4500), x2=c(4050, 4600))
mask <- convert.mask(lambda, mask.df)
