s.logo: Representation of an object in a graph by a picture

In ade4: Analysis of Ecological Data : Exploratory and Euclidean Methods in Environmental Sciences

Description

performs the scatter diagrams using pictures to represent the points

Usage

s.logo(dfxy, listlogo, klogo=NULL, clogo=1, rectlogo=TRUE,
    xax = 1, yax = 2, neig = NULL, cneig = 1, xlim = NULL, ylim = NULL, 
    grid = TRUE, addaxes = TRUE, cgrid = 1, include.origin = TRUE, 
    origin = c(0, 0), sub = "", csub = 1.25, possub = "bottomleft", 
    pixmap = NULL, contour = NULL, area = NULL, add.plot = FALSE) 

Arguments

dfxy	a data frame with at least two coordinates
listlogo	a list of pixmap pictures
klogo	a numeric vector giving the order in which pictures of listlogo are used; if NULL, the order is the same than the rows of dfxy
clogo	a numeric vector giving the size factor applied to each picture
rectlogo	a logical to decide whether a rectangle should be drawn around the picture (TRUE) or not (FALSE)
xax	the column number for the x-axis
yax	the column number for the y-axis
neig	a neighbouring graph
cneig	a size for the neighbouring graph lines used with par("lwd")*cneig
xlim	the ranges to be encompassed by the x axis, if NULL, they are computed
ylim	the ranges to be encompassed by the y axis, if NULL, they are computed
grid	a logical value indicating whether a grid in the background of the plot should be drawn
addaxes	a logical value indicating whether the axes should be plotted
cgrid	a character size, parameter used with par("cex")* cgrid to indicate the mesh of the grid
include.origin	a logical value indicating whether the point "origin" should be belonged to the graph space
origin	the fixed point in the graph space, for example c(0,0) the origin axes
sub	a string of characters to be inserted as legend
csub	a character size for the legend, used with par("cex")*csub
possub	a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft", "bottomright")
pixmap	an object 'pixmap' displayed in the map background
contour	a data frame with 4 columns to plot the contour of the map : each row gives a segment (x1,y1,x2,y2)
area	a data frame of class 'area' to plot a set of surface units in contour
add.plot	if TRUE uses the current graphics window

Value

The matched call.

  	invisible(lapply(split(w1, w1$id), function(x) polygon(x[, -1],col = "white")))
  	s.logo(capitales$xy, capitales$logo, klogo = index, add.plot = TRUE, clogo = 1) 
    # depends on pixmap
