Import the data from a biom-format file into R,
represented as an instance of the
biom-class
; essentially a
list
with special constraints that map to
the
biom-format definition.

biom_file |
(Required). A character string indicating the file location of the biom formatted file. This is a JSON formatted file specific to biological datasets. The format is formally defined at the biom-format definition |
The BIOM file format (canonically pronounced biome) is designed to be a general-use format for representing biological sample by observation contingency tables. BIOM is a recognized standard for the Earth Microbiome Project and is a Genomics Standards Consortium candidate project. Please see the biom-format home page for more details.
It is tempting to include an argument identifying the biom-format version number of the data file being imported. However, the biom-format version number is a required field in the biom-format definition. Rather than duplicate this formal specification and allow the possibility of a conflict, the version number of the biom format will be referred to only by the "format" field in the biom formatted data, or its representation in R.
An instance of the biom-class

The biom
constructor function.

## The previous examples use system.file() because of constraints in specifying a fixed
## path within a reproducible example in a package.
## In practice, however, you can simply provide "hard-link"
## character string path to your file:
# mybiomfile <- "path/to/my/biomfile.biom"
# read_biom(mybiomfile)
