crucifer (pcru) in 2001.

\format{
	\describe{
	\item{pcru.y}{matrix of observed calling indices for pcru}
	\item{pcru.bin}{matrix of detections for pcru}
	\item{pcru.data}{array of covariates measured at the
	  observation-level for pcru}

}
\details{
The rows of pcru.y, pcru.bin, pfer.y, and pfer.bin correspond to sites
and columns correspond to visits to each site.  The first 2 dimensions
of pfer.data and pcru.data are matrices of covariates that correspond to
the observation matrices (sites \eqn{\times} observation), with the 3rd
dimension corresponding to separate covariates.
