This function sums up feature intensities per analyte_id.
THis is is useful when you have multiple features (e.g. adducts, isotopes, in-source fragments) or isomers that you want to combine into a single analyte intensity value, such as LPC sn1 and sn2 species.
NOTE: This is still an experimental function! It will overwrite the feature_id in the dataset and analysis metadata of featured that share same analyte_id. Currently the original feature_id is not backed up anywhere. Use with caution and check results carefully!
Arguments
- data
MRMhubExperiment object
- qualifier_action
Character. How to handle qualifier features. To sum them up separately select "separate",
- feature_classes
Select feature classes to sum up. Default (NA) is to sum up all feature classes according to their analyte_id. to include them in the sum if quantifier select "include", to not sum them up select "exclude".
