An example LDATS dataset, functionally that used in Christensen et al. (2018). The data are counts of 21 rodent species across 436 sampling events, with the count being the total number observed across 8 50 m x 50 m plots, each sampled using 49 live traps (Brown 1998, Ernest et al. 2016).
rodents
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 (newmoon number, sin and cos of the fraction
of the year).
