For converting_to_relative_to_reference function: add aggregation function (mean) in case of multiple reference samples on 1 plex

@BelindaBGarana Sorry for the late reply! If the mean is desired in the case of multiple references, Reference = "(ref1 + ref2)/2" can be specified in the references table, where ref1 and ref2 are the IDs for the reference channels in that TMT plex. To generalize this for n references, use sprintf("(%s) / %d", paste(reference_columns, collapse = " + "), length(reference_columns)), where reference_columns is the character vector of reference columns for each plex.

I will take a look at the modification you proposed, as well.
