Group samples for rarefaction curve


I am trying to create a rarefaction curve by four different groups instead of all of my samples. I read that I'll need to group my table.qza differently and then make a phyloseq object from the new table. How could I do this?

Here is my curve and code:
rarecurve(t(otu_table(DADA2phyloseq)), step=50, cex=0.5, se= TRUE, xlim= c(0,26000), col = "blue")


Welcome to the RStudio community!

In order for us to help you with your question, please provide us a minimal reproducible example where you provide a minimal (dummy) dataset and code that can recreate the issue. Once we have that, we can go from there. For help on creating a Reprex, see this guide:

I assume you have to group and summarise the data before you plot the curve, so please be sure to provide a sample of the original data, and how you'd like to group it.

Good luck!
