### Arguments

`envfilename` | (Required). A charater string of the ENV filename (relative or absolute)
`tree` | (Optional). `phylo-class` object to be paired with the output otu_table.
`sep` | A character string indicating the delimiter used in the file. The default is `"\t"`.
`...` | Additional parameters passed on to `read.table`.

### Value

An `otu_table-class`, or `phyloseq-class` if a `phylo-class` argument is provided to `tree`.
