s.value {ade4} | R Documentation |

performs the scatter diagram with the representation of a value for a variable

s.value(dfxy, z, xax = 1, yax = 2, method = c("squaresize", "greylevel"), zmax=NULL, csize = 1, cpoint = 0, pch = 20, clegend = 0.75, neig = NULL, cneig = 1, xlim = NULL, ylim = NULL, grid = TRUE, addaxes = TRUE, cgrid = 0.75, include.origin = TRUE, origin = c(0,0), sub = "", csub = 1, possub = "topleft", pixmap = NULL, contour = NULL, area = NULL, add.plot = FALSE)

`dfxy` |
a data frame with two coordinates |

`z` |
a vector of the values corresponding to the rows of |

`xax` |
column for the x axis |

`yax` |
column for the y axis |

`method` |
a string of characters |

`zmax` |
a numeric value, equal by default to max(abs(z)), can be used to impose a common scale of the size of the squares to several drawings in the same device |

`csize` |
a size coefficient for symbols |

`cpoint` |
a character size for plotting the points, used with |

`pch` |
if |

`clegend` |
a character size for the legend used by |

`neig` |
a neighbouring graph |

`cneig` |
a size for the neighbouring graph lines used with |

`xlim` |
the ranges to be encompassed by the x, if NULL they are computed |

`ylim` |
the ranges to be encompassed by the y, 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 |

`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 |

`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 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 |

The matched call.
