title: Looking for code in R to summarize by ____H or ____D?
body: <p>I have a chart with ASV's per sample, the samples are sorted by number (sample) and a letter which corresponds to human or dog. I am trying to see which ASV's are in only humans, or only dogs. My thought for how to do this is sum all rows by dog or human, ignoring individual samples, and see values of 0 or greater than zero.</p>
  <p>I am unsure of code, have tried a few things but none have worked. Mainly working with phyloseq and DESeq2.<a href="https://i.stack.imgur.com/DecUz.jpg" rel="nofollow noreferrer">This is the table Im working with, 11,000 ASV samples.</a></p>
