polyboxplotmap {GeoXp}R Documentation

Interactive polyboxplot and map

Description

Parallel Boxplots of a numerical variable by levels of a factor. It interacts with a map.

Usage

polyboxplotmap(long, lat, var1, var2, varwidth=FALSE,listvar = NULL, listnomvar = NULL,
carte = NULL, criteria = NULL, label = "", cex.lab=1, names.arg = "", xlab = "",
ylab= "count", pch = 16, col = "grey", axes = FALSE, lablong = "", lablat = "")

Arguments

long a vector x of size n
lat a vector y of size n
var1 a vector of factor of size n
var2 a vector of numerical values of size n
varwidth if varwidth is TRUE, the boxes are drawn with widths proportional to the square-roots of the number of observations in the groups
listvar matrix of variables which permit to plot bubbles on map or add a graphic using the tk window
listnomvar a list with names of variables listvar
carte matrix with 2 columns for drawing spatial polygonal contours : x and y coordinates of the vertices of the polygon
criteria a vector of size n of boolean which permit to represent preselected sites with a cross, using the tcltk window
label a list of character of size n with name of site. Names are printed on map after a selection
cex.lab character size of label
names.arg names of factors of var1
xlab a title for the graphic x-axis
ylab a title for the graphic y-axis
pch 16 by default, symbol for selected points
col "grey" by default, color of the points of the scatter plot
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

Each site is associated to a value of a level of $var1$ and of a value of $var2$. There is an interactivity only in one direction : the sites selected by quartile-intervals on one of the boxplots are then represented on the map in red (or colors according to the options).

Value

A vector of boolean of size $n$. TRUE if the site was in the last selection.
