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
