sites

design

subpop

The data.cat data frame of categorical response variables.

data.cat

The data.cont data frame of continuous response variables.

data.cont

The data.ar or data.rr data frame of categorical response
and stressor variables.

data.risk

The names for the design data frame.

design.names

This function checks site IDs, the sites data frame, the subpop data frame,
the data.cat data frame, the data.cont data frame, the data.ar data frame,
and the data.rr data frame to assure valid contents. If they do not exist,
then the sites data frame and the subpop data frame are created.

These functions provide procedures for selecting sites for spatial
surveys using spatially balanced algorithms applied to discrete points,
linear networks, or polygons. The probability survey designs available
include independent random samples, stratified random samples, and unequal
probability random samples (categorical or probability proportional to
size). Design-based estimation based on the results from surveys is
available for estimating totals, means, quantiles, CDFs, and linear models.
The analyses rely on package survey for most results. Variance estimation
options include a local neighborhood variance estimator that is appropriate
for spatially-balanced survey designs. A reference for the survey design
portion of the package is: D. L. Stevens, Jr. and A. R. Olsen (2004),

Statistical Association 99(465): 262-278, <DOI:10.1198/016214504000000250>.
