arguments passed through
auxvar
a vector containing the names of columns in the data slot of the
SpatialDesign object that identify auxiliary variables to be used to
summarize the survey design or create plots of the survey design. The
default is NULL.
spframe
an sp package object of class SpatialPointsDataFrame,
SpatialLinesDataFrame, or SpatialPolygonsDataFrame that
contains the survey design frame. The default is NULL.
tess_ind
a logical variable indicating whether spatial balance metrics
are calculated using proportions obtained from the intersection of Dirichlet
tesselation polygons for the sample points with the frame object. TRUE means
calculate the metrics. FALSE means do not calculate the metrics. The
default is TRUE
sbc_ind
a logical variable indicating whether spatial balance metrics
are calculated using proportions obtained from a rectangular grid
superimposed on the sample points and the frame. TRUE means calculate the
metrics. FALSE means do not calculate the metrics. The default is FALSE.
nrows
number of rows (and columns) for the grid of cells. The default
is 5.
dxdy
indicator for equal x-coordinate and y-coordinate grid cell
increments, where TRUE means the increments are equal and FALSE means the
increments are not equal. The default is TRUE.
stratum
name of the column from the data slot of the spframe object
that identifies stratum membership for each element in the frame. If
stratum equals NULL, the design is unstratified, and a column named
"stratum" (with all its elements equal to the stratum name specified in
design) is added to the data slot of the spframe object. The default is
NULL.
mdcaty
name of the column from the data slot of the spframe object that
identifies the unequal probability category for each element in the frame.
The default is NULL.
pdffile
a character variable containing the name of the pdf file to
which output is written. If a value is not provided, output is written to
the graphics window. The default is NULL.
width
width of the graphic region in inches. The default is 8.
height
height of the graphic region in inches. The default is 10.
