spectrolab can resample spectra using the method
resample. Since version 0.19, spectrolab uses a gaussian
model that takes the Full Width at Half Maximum or
FWHM to compute the spectrum values at the new
bands.
Here s a quick example.
dir_path = system.file("extdata/svc_raw_and_overlap_matched_serbin/SVC_Files_moc", package = "spectrolab")
s_raw = read_spectra(dir_path)
new_bands = seq(400, 2400, 5)
fwhm = make_fwhm(s_raw, new_bands)
#> setting k to the number of unique band diff values
s_resamp = resample(s_raw,new_bands = new_bands, fwhm = fwhm)
plot(s_raw, lwd = 0.5)
plot(s_resamp, add = TRUE, lwd = 0.25, col = "red")
