## 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)
