Hi
I have 100 samples (50 patients each with 2 samples), and sample data variables "sampleID" which is unique, "patientID" which is duplicated (because each patient was sampled at 2 sites, A & B) and "sample_site" variable which is either A or B.

I would like to carry out a within patient comparison (intra-individual) of the different sample collection sites. Specifically, since each patient was sampled at two sites, A & B for instance, and I would like to check if these two sites differ within the same patient.

Could you kindly advice me on the how (code wise) I can perform this analysis in vegan?
Any ideas to visualise these differences/similarities at individual level?

Thanks in advance,
Nelly
