Hi, I am using R codes for phyloseq analysis with qiime2 2011.18 data. it is showing some error.

I am using codes from this link:

Error:

biom_data <- import_biom(BIOMfilename = "/Users/3052771/Desktop/Phyloseq-qiime2/Phyloseq/table-with-taxonomy.biom", treefilename = "/Users/3052771/Desktop/Phyloseq-qiime2/Phyloseq/tree.nwk")


Warning message:

It will be a great help if you can suggest how I can resolve it.
