s.match: Plot of Paired Coordinates

Description

performs the scatter diagram for a paired coordinates.

Usage

s.match(df1xy, df2xy, xax = 1, yax = 2, pch = 20, cpoint = 1, 
    label = row.names(df1xy), clabel=1, edge = 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 data frame containing two columns from the first system

df2xy

a data frame containing two columns from teh second system

xax

the column number for the x-axis of both the two systems

yax

the column number for the y-axis of both the two systems

pch

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

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

edge

If TRUE the arrows are plotted, otherwise only the segments are 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 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

aan 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 line (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

Examples

X <- data.frame(x = runif(50,-1,2), y = runif(50,-1,2))
Y <- X + rnorm(100, sd = 0.3)
par(mfrow = c(2,2))
s.match(X, Y)
s.match(X, Y, edge = FALSE, clab = 0)
s.match(X, Y, edge = FALSE, clab = 0)
s.label(X, clab = 1, add.plot = TRUE)
s.label(Y, clab = 0.75, add.plot = TRUE)
s.match(Y, X, clab = 0)
