Residuals for each signature

Represents each signature as a weighted combination of endmembers. This function generates a table which contains the residuals of this adjustment: the sum of the errors between the represented and the real values.

table_residuals_summary(signatures)

Arguments

signatures	A spectral object built using the load_signature_files function. The spectral object needs to be unmixed (using unmixing_fixed or unmixing_vca).

Value

A matrix object with the tabular information.

Examples

data(signatures)
unmixed_signatures <- unmixing_fixed(signatures, files=c("almagre.asd.txt", "blanco.asd.txt"))
#> Error in unmixing_fixed(signatures, files = c("almagre.asd.txt", "blanco.asd.txt")): unused argument (files = c("almagre.asd.txt", "blanco.asd.txt"))
table_residuals_summary(unmixed_signatures)
#> Error in is(x, "spectral"): object 'unmixed_signatures' not found
