Drawing a graphic

Description

The function ‘graphique’ draws a specific graphic. Possibility to draw one of these graphics : Histogram, Barplot, Boxplot, Polyboxplot, Scatterplot, Densityplot, Neighbourplot, Lorentz, Moran, Angleplot, Variocloud, Cluster and PCA (graphics of individuals and variables). This function is called in most of the functions of GeoXp (this is not an interactive function).

Arguments

var1

1st variable of size n

var2

2nd variable of size n

var3

3rd variable of size n (used for variocloudmap)

obs

a vector of boolean of size n with sites selected

num

number of windows which must be activated (3 ou 4)

graph

name of graphic which must be drawn : Histogram, Barplot, Boxplot, Polyboxplot, Scatterplot, Densityplot1, Densityplot2, Neighbourplot, Lorentz, Moran, Quadrant, Angleplot, Variocloud, Cluster, Acp1, Acp2

couleurs

Possibilty to change colors on the graphic

symbol

choice of representation of selected sites

labvar

name(s) of variable(s) studied

nbcol

number of cells if the graphic choosen is the histogram (10 by default)

alpha1

regression smoothing paramater

W

Spatial weight matrix

Xpoly

x-coordinates of the vertices of selected polygon

Ypoly

y-coordinates of the vertices of selected polygon

F

Used for Ginimap

G

Used for Ginimap

opt1

Option for adding a curve (regression line or conditionnal quantile depending on the function)

opt2

Option for drawing robust empirical variogram

quantiles

vector which contains the values of alpha for conditionnal quantile

labmod

names of factor if the graphic choosed is a barplot

direct

Used for PCA

inertie

Used for PCA

label

Name of sites

kernel

Name of the kernel choosed in densitymap

obsq

Used for clustermap and barmap

locmoran

Print local moran for each site

bin

The bins chosen to calculate empirical variogram

cex.lab

character size of label

buble

For Local Moran plot only : a boolean with TRUE for drawing bubbles, FALSE otherwise

cbuble

For Local Moran plot only : vector of size n with size of each site depending on variable with which bubbles are constructed

legmap

For Local Moran plot only : a list of (numeric,numeric,numeric,numeric,numeric,numeric,character) with the sizes and the corresponding values of the 3 bubbles represented in the legend and the variable name of variable choosed

legends

For Local Moran plot only : a list of c(boolean,boolean,c(numeric,numeric),c(numeric,numeric)) with TRUE for drawing legends of bubbles (1st argument) or factors (2nd argument) and the coordinates of the location of the upper left corner of the legend box

xlim

the x limits of the plot

ylim

the y limits of the plot

Details

This function is called by any function which draws a graphic. A lot of options are considered because of the large number of graphics proposed

Value

No values, only drawing of a graphic
