sample_data-class), which in the
phyloseq-package is represented as a
special extension of the data.frame-class.
When the argument is a data.frame,
sample_data will create a sample_data-class
object. In this case, the rows should be named to match
the sample_names of the other objects to
which it will ultimately be paired. Alternatively, if the
first argument is an experiment-level
(phyloseq-class) object, then the
corresponding sample_data is returned. Like other
accessors (see See Also, below), the default behavior of
this method is to stop with an error if object is
a phyloseq-class but does not contain a
sample_data.
sample_data(object, errorIfNULL=TRUE)data.frame-class, or a
phyloseq-class object.NULL)? Default TRUE.sample_data-class object representing the
sample variates of an experiment.
