| ncol {hyperSpec} | R Documentation |
nrow yields the number of rows in x@data, i.e. the
number of spectra in the hyperSpec object.
ncol returns the number of columns in x@data. I.e. the
number of columns with additional information to each spectrum
(e.g. "x", "y", ...) + 1 (for column spc containing the spectra).
nwl returns the number of columns in x@data$spc,
i.e. the length of each spectrum.
dim returns all three values in a vector.
