## Plot of the factorial maps for the projection of a vector basis

### Description

performs the scatter diagrams of the projection of a vector basis.

### Usage

    s.arrow(dfxy, xax = 1, yax = 2, label = row.names(dfxy),
        clabel = 1, pch = 20, cpoint = 0, boxes = TRUE, edge = TRUE, origin = c(0,0),
        xlim = NULL, ylim = NULL, grid = TRUE, addaxes = TRUE, cgrid = 1,
        sub = "", csub = 1.25, possub = "bottomleft", pixmap = NULL,
        contour = NULL, area = NULL, add.plot = FALSE)

### Arguments

`dfxy` | a data frame containing the two columns for the axes
`xax` | the column number of x in `dfxy`
`yax` | the column number of y in `dfxy`
`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.
`boxes` | if TRUE, labels are framed
`edge` | a logical value indicating whether the arrows should be plotted
`origin` | the fixed point in the graph space, by default c(0,0) the origin of axes. The arrows begin at `cent`.
`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
`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 legend 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 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.
