No possibility to include a source_factor to fit with mix data when loading sources, why? Thank you!

Hi,

When loading sources, I'm trying to set source_factors as "Sector", to fit with the same "Sector" I did include in my "Load datamix". I did try different configurations, but always ending up with the same error message :

Error in list.sources.bylev[[lev]] <- SOURCE[SOURCE[, source_factors] == :
attempt to select less than one element in integerOneIndex

Because I do detect significatively differents values for my sources between my 6 different "Sector", and because I'm trying to compare those, I think it's very important to get it right. If I can't, I will have to deal with every Sector independtly, but it's going to arise the error.

Here's my loading code if it can help someone to help me:

#Load datamix

mix <- load_mix_data(
filename = "temp_consumers.csv",
iso_names = c("d13C","d2H"),
factors = c("Taxa","Sector"),
fac_random = c(FALSE, FALSE),
fac_nested = c(FALSE, FALSE),
cont_effects = NULL)

source <- load_source_data(
filename="temp_sources.csv",
source_factors="Sector",
conc_dep=FALSE,
data_type="raw", mix)

Error in list.sources.bylev[[lev]] <- SOURCE[SOURCE[, source_factors] == :
attempt to select less than one element in integerOneIndex

Thank you very much for your help!
