s.match.class {ade4} | R Documentation |

Performs a graphical representation of two sets of coordinates (different colors and symbols) and a partitionning into classes

s.match.class(df1xy, df2xy, fac, wt = rep(1/nrow(df1xy), nrow(df1xy)), xax = 1, yax = 2, pch1 = 16, pch2 = 15, col1 = rep("lightgrey", nlevels(fac)), col2 = rep("darkgrey", nlevels(fac)), cpoint = 1, label = levels(fac), clabel = 1, cstar = 1, cellipse = 0, axesell = 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)

`df1xy` |
a dataframe with the first system of coordinates |

`df2xy` |
a dataframe with the secocnd system of coordinates |

`fac` |
a factor partitioning the rows of the data frame in classes |

`wt` |
a vector of weights |

`xax` |
a number indicating which column should be plotted on the x-axis |

`yax` |
a number indicating which column should be plotted on the x-axis |

`pch1` |
if `cpoint` > 0, an integer specifying the symbol or the single character to be used for plotting points |

`pch2` |
if `cpoint` > 0, an integer specifying the symbol or the single character to be used for plotting points |

`col1` |
a color for symbols |

`col2` |
a color for symbols |

`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` |

`cstar` |
a number between 0 and 1 which defines the length of the star size |

`cellipse` |
a positive coefficient for the inertia ellipse size |

`axesell` |
a logical value indicating whether the ellipse axes should be 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 belong to the graph space |

`origin` |
a fixed point in the graph space, for example c(0,0) for the origin of 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` |
a `pixmap` object |

`contour` |
a dataframe with 4 columns to plot the contour of the map : each row gives a segment (x1,y1,x2,y2) |

`area` |
a dataframe of class 'area' to plot an areal map |

`add.plot` |
if TRUE, add the plot to the current graphic device |
