sub-.spectra: Subsets a spectra object
In annakat/casper_defunct: Class and methods for hyperspectral data

Description Usage Arguments Details Value

Subsets spectra objects by sample names (rows) or wavelengths (columns).

1 2	## S3 method for class 'spectra' this[i, j, verbose = FALSE]

`i`	Sample names (preffered) or index.
`j`	Wavelength labels, as numeric or characeter. Do not use indexes.

Subset operations based on samples (first argument) will match either sample names or indexes, in that order. That is, if you subset x[1:2 , ] and your sample names contain 1 and 2, you will get the spectra with names c(1, 2) and not (at least necessarily) the first and second samples in the 'spectra' object.
