read.dbf

Name of the dbf file without any extension. If filename
equals a dbf file name, then that dbf file is read. If filename equals
NULL, then all of the dbf files in the working directory are read. The
default is NULL.

filename

This function reads either a single dbf file or multiple dbf files. For
multiple dbf files, all of the dbf files must have the same variable names.

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>.
