Plot Sample from a GRTS Design for a Finite Resource

Description

Plot finite resource sample frame and sites from survey design based on panel, strata, and multi-density categories.

Usage

plot.ptsdsgn(sframe, sitex, sitey, panel, stratum=NULL, mdcaty=NULL, sname=NULL,
   col=c("Black", "Gray", "Red", "Blue"), pch=20, cex=1, legloc="BR",
   xjustnew=NULL, yjustnew=NULL, ...)

Arguments

sframe a sample frame, which must have id, x, y, stratum, and mdcaty variables.
sitex the x-coordinate for site, which must be the same projection as linseg.
sitey the y-coordinate for site, which must be the same projection as linseg.
panel the panel membership for site, which must be a factor.
stratum the stratum membership for site, which must be a factor. The default is NULL.
mdcaty the multi-density category for site, which must be a factor. The default is NULL.
sname study name for plot titles. The default is NULL.
col the vector of colors that are used sequentially. The default is: c("Black", "Gray", "Red", "Blue").
pch the plot character for sample sites. The default is 20.
cex the amount by which the character size for the plot character should be scaled. The default is 1.
legloc the location for plot legend: "BR"=Bottom Right, "BL"=Bottom Left, "TR"=Top Right, and "TL"=Top Left. The default is "BR".
xjustnew how the legend is to be justified relative to the legend x location: 0 means left justified, 0.5 means centered, and 1 means right justified. The default is NULL, which results in a value of 0.
yjustnew how the legend is to be justified relative to the legend y location: 0 means left justified, 0.5 means centered, and 1 means right justified. The default is NULL, which results in a value of 1.
... additional arguments for plot()

Details

The function generates a series of plots of the linear network and sites based on the survey design structure.

Value

A series of plots that are best viewed by placing in a pdf output file.
