## 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.
