Hi! Sorry if this is a duplicate but I have searched through the forum and can't find an answer to this question:
I have been trying out the qiime2 sample-classifier methods as an alternative to running classifiers with different R packages.
I'm wondering why the methods implemented by this plug-in require FeatureTable[Frequency] artifacts and don't accept presence/absence or relative abundance data?
If I import a presence/absence table as a FeatureTable[Frequency] artifact the methods seem to work fine, but I am worried that I am violating assumptions somewhere in the method and can't be sure.
Thanks for any advice/help!
