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).
nrow()
yields the number of rows in x@data
, i.e. the number of
spectra in the hyperSpec
object.
nwl()
returns the number of columns in x@data$spc
, i.e. thelength of
each spectrum.
dim()
returns all three values in a vector.
