selectstat: Selection of values on a graphic

In tibo31/GeoXp: Interactive Exploratory Spatial Data Analysis

Selection of values on a graphic

Description

The function selectstat() is used to select sites on a graphic such as Histogram, Barplot, Boxplot, Polyboxplot, Scatterplot, Densityplot, Neighbourplot, Lorentz, Moran, Angleplot, Variocloud, Cluster, or PCA. Most of the GeoXp functions call selectstat.r.

Usage

selectstat(var1, var2, obs, Xpoly, Ypoly, method,
  nbcol, W, F, long, lat)

Arguments

var1	1st variable of size n
var2	2nd variable of size n
obs	a boolean vector of size n : TRUE if a site is already selectioned, FALSE otherwise.
Xpoly	X-coordinates of the vertices of selected polygon
Ypoly	Y-coordinates of the vertices of selected polygon
method	name of the graph wich must be drawn among Histogram, Barplot, Boxplot, Polyboxplot, Densityplot, Neighbourplot, Lorentz, Anglepoint, Variopoint
nbcol	nbcol : number of cells for the histogram (10 by default)
W	A matrix of size n \times n (for spatial weight)
F	a vector of numeric
long	a vector of x-axis of size n
lat	a vector of y-axis of size n

Details

This function is not an interactive function.

Value

Return a vector of boolean of size n with TRUE if sites have been selected on a graph
