## Scatter Plot

### Description

performs the scatter diagrams with labels.

### Usage

    s.label(dfxy, xax = 1, yax = 2, label = row.names(dfxy),
        clabel = 1, pch = 20, cpoint = if (clabel == 0) 1 else 0,
        neig = NULL, cneig = 2, 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
`xax` | the column number for the x-axis
`yax` | the column number for the y-axis
`label` | a vector of strings of characters for the point labels
`clabel` | if not NULL, a character size for the labels, used with `par("cex")*clabel`
`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
`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 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

    s.label(mafragh$xy, inc = FALSE, neig = mafragh$neig, addax = FALSE)
    data(irishdata)
    s.label(irishdata$xy, inc = FALSE, contour = irishdata$contour,
        addax = FALSE)

    par(mfrow = c(2,2))
    cha <- ls()
    s.label(cbind.data.frame(runif(length(cha)),
        runif(length(cha))), lab = cha)
    x <- runif(50,-2,2) ; y <- runif(50,-2,2) ; z <- x^2 + y^2
    s.label(data.frame(x,y), lab = as.character(z < 1))
    s.label(data.frame(x,y), clab = 0, cpoi = 1, add.plot = TRUE)
