plot3D_dif {TSCS}

Plot Interior Spatial Locations and System Boundary - 3D Map

Description

plot3D_dif differentiates boundary and interior spatial locations in a spatial domain (a collection of spatial locations with their coordinates). Since TSCS method is only capable of interpolation but not extrapolation, it is necessary to highlight the difference between interior spatial locations and system boundary.

Usage

plot3D_dif(coords, h1, h2, v, xlab = NULL, ylab = NULL, zlab = NULL,
  title = NULL, cex = 3)

Arguments

coords

data frame; should only contain the three variables: X coordinate, Y coordinate and Z coordinate. Each row uniquely denotes a spatial location. (coordinates must be numeric)

h1

numeric; side length of the unit cubic grid in X coordinate direction (horizontal).

h2

numeric; side length of the unit cubic grid in Y coordinate direction (horizontal).

v

numeric; side length of the unit cubic grid in Z coordinate direction (vertical).

xlab

a label for the x axis, defaults to the name of X coordinate.

ylab

a label for the y axis, defaults to the name of Y coordinate.

zlab

a label for the z axis, defaults to the name of Z coordinate.

title

a main title for the plot.

cex

numeric; size of point to be plotted for each spatial location. (default: 3)

Details

• The resulting plot is interactive, where the red points are interior spatial locations while the black points denote system boundary.

• plot3D_dif is exclusive to 3D rectangular grid system. Similarly, if you want to fathom how this package handles 2D rectangular grid system, please refer to plot_dif.

Examples

## Not run: 

## TSCS spatial interpolation procedure:

basis <- tscsRegression3D(data = data, h1 = 3.75, h2 = 2.5, v = 5, alpha = 0.01);
basis$percentage
est <- tscsEstimate3D(matrix = basis$coef_matrix, newdata = newdata, h1 = 3.75, h2 = 2.5, v = 5);
str(est)

## comparison of estimates and true values:

plot_compare(est = est$estimate[,4], true = true)
index <- appraisal_index(est = est$estimate[,4], true = true);
index

## data visualization:

plot3D_dif(data = data[,1:3], h1 = 3.75, h2 = 2.5, v = 5)
plot3D_NA(newdata = newdata)
plot3D_map(newdata = newdata)
