s.match: Plot of Paired Coordinates

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

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 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.

  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)
  par(mfrow = c(1, 1))
