Convert an object of class generic_mspct
or a derived class into an R
matrix with wavelengths saved as an attribute and spectral data in rows or
columns.
# S3 method for generic_mspct
as.matrix(x, spct.data.var, byrow = attr(x, "mspct.byrow"), ...)mspct2mat(x, spct.data.var, byrow = attr(x, "mspct.byrow"), ...)
generic_mspct object.
character The name of the variable containing the spectral data.
logical. If FALSE (the default) the matrix is filled with the spectra stored by columns, otherwise the matrix is filled by rows.
currently ignored.
This conversion preserves the spectral data but discards almost all the metadata contained in the spectral objects. In other words a matrix created with this function cannot be used to recreate the original object unless the same metadata is explicitly supplied when converting the matrix into new collection of spectra.
