histobarmap {GeoXp}R Documentation

Histogram, barplot and map

Description

The function `histobarmap' draws a bar plot (vertical bar) of the given variable $var1$, a histogram of the given variable $var2$ and a map with sites of coordinates $(long,lat)$.

Usage

histobarmap(long, lat, var1, var2, criteria = NULL, 
            carte = NULL, label = "", symbol = 0, color = 1, 
            nbcol = 10, labvar = c("", ""), labmod = "", 
            listvar = NULL, listnomvar = NULL, axis = 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
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 of $var1$
symbol 0 or 1, choice of representation of selected points. If 0, selected points are circles, if 1, selected points are stars
nbcol number of cells for histogram (10 by default)
labvar list of names for variable `var1' and `var2'
labmod names of factors `var'
listvar matrix of variables fo size $n times p$ for optional additional graph and bubbles
listnomvar list of character of size $p$ with names of variables in 'listvar'
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

Each site is associated to a factor of $var1$ and to a value of $var2$. There is interactivity between the three windows created : the sites selected by a bar on the bar plot or on the histogram are represented on the map in red and the value and factor of sites selected on the map are represented in red on the bar plot and on the histogram.

Value

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