barmap {GeoXp}R Documentation

Interactive Bar plot and map

Description

The function `barmap' draws a bar plot (vertical bar) of the given factor variable $var$ and a map with sites of coordinates $(long,lat)$.

Usage

barmap(long, lat, var, listvar = NULL, listnomvar = NULL, 
       criteria = NULL, carte = NULL, label = "", color = 1, 
       symbol = 0, labvar = "", labmod = "", axis = FALSE, 
       lablong = "", lablat = "")

Arguments

long a vector $x$ of size $n$
lat a vector $y$ of size $n$
var a vector of factor of size $n$
listvar matrix of variables fo size $n times p$ for optional additional graph and bubbles
listnomvar list of character of size $p$ with name of variables from $listvar$
criteria a vector of size n of boolean with TRUE on specific sites (these for non interactive selection)
carte matrix with 2 columns for drawing spatial polygonal contours : $x$ and $y$ coordinates of the vertices of the polygon
label vector of character of size $n$ with name of each site
color 0 or 1, choice of representation of selected points. If 0, sites are represented in blue, if 1, sites are represented with different colors for each factor
symbol 0 or 1, choice of representation of selected points. If 0, selected points are circles, if 1, selected points are stars
labvar name of variable $var$
labmod names of factors of $var$
axis 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

The selection of a bar on the bar plot results in the corresponding sites coloured on the map with the corresponding colour observed on the bar. Reversely, the selection of sites on the map by `points' or `polygon' results in the drawing of the sub-barplot in red.

Value

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