s.match.class: Scatterplot of two sets of coordinates and a partionning into classes

Description

Performs a graphical representation of two sets of coordinates (different colors and symbols) and a partitionning into classes

Usage

s.match.class(df1xy, df2xy, fac, wt = rep(1/nrow(df1xy), nrow(df1xy)), xax = 1, yax = 2, pch1 = 16, pch2 = 15, col1 = rep("lightgrey", nlevels(fac)), col2 = rep("darkgrey", nlevels(fac)), cpoint = 1, label = levels(fac), clabel = 1, cstar = 1, cellipse = 0, axesell = TRUE, 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

df1xy

a dataframe with the first system of coordinates

df2xy

a dataframe with the secocnd system of coordinates

fac

a factor partitioning the rows of the data frame in classes

wt

a vector of weights

xax

a number indicating which column should be plotted on the x-axis

yax

a number indicating which column should be plotted on the x-axis

pch1

if cpoint > 0, an integer specifying the symbol or the single character to be used for plotting points

pch2

if cpoint > 0, an integer specifying the symbol or the single character to be used for plotting points

col1

a color for symbols

col2

a color for symbols

cpoint

a character size for plotting the points, used with par("cex")*cpoint. If zero, no points are drawn

label

a vector of strings of characters for the couple labels

clabel

if not NULL, a character size for the labels, used with par("cex")*clabel

cstar

a number between 0 and 1 which defines the length of the star size

cellipse

a positive coefficient for the inertia ellipse size

axesell

a logical value indicating whether the ellipse axes should be drawn

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 belong to the graph space

origin

a fixed point in the graph space, for example c(0,0) for the origin of 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

a pixmap object

contour

a dataframe with 4 columns to plot the contour of the map : each row gives a segment (x1,y1,x2,y2)

area

a dataframe of class 'area' to plot an areal map

add.plot

if TRUE, add the plot to the current graphic device

Value

• The matched call.

Examples

xy <- data.frame(matrix(rnorm(100),50,2))
xy[,1] <- xy[,1] + rep(seq(0,12,by=3),rep(10,5))
xy[,2] <- xy[,2] + rep(seq(0,12,by=3),rep(10,5))
fac <- gl(5,10)
xy2<-xy + matrix(rnorm(100),50,2) + 1
s.match.class(xy,xy2,fac)
