read_biom(src, ...)

Value

An rbiom object.

Arguments

src

Input data as either a file path, URL, or JSON string. BIOM files can be formatted according to version 1.0 (JSON) or 2.1 (HDF5) specifications, or as classical tabular format. URLs must begin with http://, https://, ftp://, or ftps://. JSON files must have { as their first character. Compressed (gzip or bzip2) BIOM files are also supported.
