I have two Phyloseq objects with partly overlapping sample_names() and sample_data(), generated with different markers. Now I would like to merge both sets into one Phyloseq object. I would rename the taxa_names() with a prefix, e.g. \"18S_\" and \"COI_\", which would modify these identifiers in the otu_table(). Where is the object that links OTUs to samples? I'm assuming that would need to be altered as well before merging. Point being I don't want the taxa_names() to be added together, but append the otu_table() of the finished object - so that in the end I have one Phyloseq object, with one OTU table comprising of OTUs from each marker. I checked the help, but was hoping that you could give some information of how to achieve this particular task - I will edit taxa_names() and sample_data() but am unsure where to find OTU assignemnt to sample_data(). Thank you and kind regards, I hope this all makes sense and Kind regards, Cheers, Paul"}}
