The mean of every by
data points in the spectra is calculated.
spc.bin(spc, by = stop("reduction factor needed"), na.rm = TRUE, ...)

Using na.rm = TRUE
always takes about twice as long as na.rm = FALSE
.
If the spectra matrix does not contain too many NA
s, na.rm = 2
is faster than
na.rm = TRUE
.
A hyperSpec
object with ceiling (nwl (spc) / by)
data points per spectrum.
