A list
of two data.frame
-class objects with rows
corresponding to documents (sampling events). One element is the
document term table (called document_term_table
), which contains
counts of the species (terms) in each sample (document), and the other is
the document covariate table (called document_covariate_table
)
with columns of covariates (time step, year, season).
