Interactive Plot3d and map

Description

The function plot3dmap() draws a 3d-plot of three given variables $names.var$ and a map with sites of coordinates coordinates(sp.obj).

Usage

plot3dmap(sf.obj, names.var, box = TRUE,  
  criteria = NULL, carte = NULL, identify = NULL, cex.lab = 0.8,
  pch = 16, col = "lightblue3", xlab = "", ylab = "", zlab = "", 
  axes = FALSE, lablong = "", lablat = "")

Arguments

sf.obj	object of class sf
names.var	a vector of three characters; attribute names or column numbers in attribute table
box	a boolean with TRUE for drawing a box on the scatterplot 3d
criteria	a vector of boolean of size the number of Spatial units, which permit to represent preselected sites with a cross, using the tcltk window
carte	matrix with 2 columns for drawing spatial polygonal contours : x and y coordinates of the vertices of the polygon
identify	if not NULL, the name of the variable for identifying observations on the map
cex.lab	character size of label
pch	16 by default, symbol for selected points
col	"lightblue3" by default, color of bars on the histogram
xlab	a title for the graphic x-axis
ylab	a title for the graphic y-axis
zlab	a title for the graphic z-axis
axes	a boolean with TRUE for drawing axes on the map
lablong	name of the x-axis that will be printed on the map
lablat	name of the y-axis that will be printed on the map

Details

Sites selected on the map by ‘points’ or ‘polygon’ are represented in red in the 3-d plot.

Value

In the case where user click on save results button, a vector of integer is created as a global variable in last.select object. It corresponds to the number of spatial units selected just before leaving the Tk window.

Note

This function uses the rgl package and open a rgl device.

Examples

## Not run:  
# data on price indices of real estate in France
data(immob, package = "GeoXp")

# immob is a data.frame object. We have to create
# a Spatial object, by using first the longitude and latitude
require(sf)
immob.sf <- st_as_sf(immob, coords = c("longitude", "latitude"))
# optional : we add some contours that don't correspond to the spatial unit
# but are nice for mapping
midiP <- st_read(system.file("shapes/region.shp", package="GeoXp")[1])
# an example of plot3dmap
plot3dmap(immob.sf, c("prix.vente", "prix.location", "variation.vente"),
  box = FALSE, carte = midiP, identify = "Nom", cex.lab = 0.5,
  xlab = "prix.vente", ylab = "prix.location", zlab = "variation.vente")

######
# data eire
eire <- st_read(system.file("shapes/eire.shp", package="spData")[1])

# an example of use
plot3dmap(eire, c("A", "RETSALE", "INCOME"), 
  xlab = "A", ylab = "RETSALE", zlab = "INCOME")
