load_bbs_data

<code>load_bbs_data</code> loads the raw, unstratified BBS data into the current R session.
The data must have been previously fetched using the <code>fetch_bbs_data</code> function.
Note that this function is not necessary to run a Bayesian analysis of BBS data;
calling <code>stratify</code> will return stratifed BBS data in a list of data frames.

The North American Breeding Bird Survey (BBS) is a long-running
program that seeks to monitor the status and trends of the breeding birds in
North America. Since its start in 1966, the BBS has accumulated over 50 years
of data for over 500 species of North American Birds. Given the temporal and
spatial structure of the data, hierarchical Bayesian models are used to assess
the status and trends of these 500+ species of birds. 'bbsBayes' allows you to perform
hierarchical Bayesian analysis of BBS data. You can run a full
model analysis for one or more species that you choose, or you can take
more control and specify how the data should be stratified, prepared
for 'JAGS', or modelled. The functions provided here allow you to replicate
analyses performed by the United State Geological Survey (USGS, see Link
and Sauer (2011) <doi:10.1525/auk.2010.09220>) and Canadian Wildlife Service
(CWS, see Smith and Edwards (2020) <doi:10.1101/2020.03.26.010215>).

Hierarchical Bayesian Analysis of North American BBS Data

Adam C. Smith

load_bbs_data function

<dl><dt>level</dt>
<dd>A string, either "state" or "stop", specifying which counts to
load. Defaults to "state", which provides counts beginning in 1966,
aggregated in five bins, each of which contains cumulative counts from 10 of
the 50 stops along a route. Specifying "stop" provides stop-level data
beginning in 1997, which includes counts for each stop along routes
individually. Note that stop-level data is not currently supported by
the modeling utilities in bbsBayes.</dd></dl>
