Empty hyperSpec Object

Source: R/empty.R

Empty produces an hyperSpec object with the same columns and wavelengths as x. The new object will either contain no rows at all (default), or the given number of rows with all data initialized to spc and extra, respectively.

empty(x, nrow = 0, spc = NA, extra = NA)

Arguments

x

hyperSpec object
nrow

number of rows the new object should have
spc

value to initialize the new spectra matrix with
extra

value to initialize the new extra data with
