Phyloseq taxa don't match error, but TRUE when asked if values match? about phyloseq

[hank00000]

Note that I've also tried the as.matrix() trick offered in another post, but this didn't change the error. I'd really appreciate any insight.

Hi @hank00000

Can you try:

relnormps <- phyloseq(otu_table(Relative_Abundance),   # data.frame
                      sample_data(metadata_subset),    # data.frame
                      tax_table(as.matrix(tax_table))) # matrix

Hi @hank00000

Can you try:

relnormps <- phyloseq(otu_table(Relative_Abundance, taxa_are_rows = TRUE), # data.frame + sample_data(metadata_subset), # data.frame + tax_table(as.matrix(tax_df))) #matrix

Error in validObject(.Object) : invalid class “phyloseq” object:
Component taxa/OTU names do not match.
Taxa indices are critical to analysis.
Try taxa_names()

Checked and the above TRUEs are still valid.

Hi @hank00000 Hmm, that's strange, How about:

# Check taxa names
identical(taxa_names(otu_table(Relative_Abundance, taxa_are_rows = TRUE)), 
          taxa_names(tax_table(as.matrix(tax_df))))

# Check sample names
identical(sample_names(otu_table(Relative_Abundance,, taxa_are_rows = TRUE)), 
          sample_names(sample_data(metadata_subset)))

Please use the code block markdown for better visualization out of your output.

For example:

``` r
x <- sum(c(1, 2, 3, 4))
x
```
