graph.var | R Documentation |

Plot the graphs of the variables after a Factor Analysis.

```
graph.var(x, axes = c(1, 2),
xlim = NULL, ylim = NULL, col.sup = "blue",
col.var = "black", draw="all", label=draw, lim.cos2.var = 0.1,
cex = 1, title = NULL, new.plot = TRUE, ...)
```

`x` |
an object of class PCA, MCA, MFA or HMFA |

`axes` |
a length 2 vector specifying the components to plot |

`xlim` |
range for the plotted 'x' values, defaulting to the range of the finite values of 'x' |

`ylim` |
range for the plotted 'y' values, defaulting to the range of the finite values of 'y' |

`col.sup` |
a color for the quantitative supplementary variables |

`col.var` |
a color for the variables |

`draw` |
a list of character for the variables which are drawn (by default, all the variables are drawn). You can draw all the active variables by putting "var" and/or all the supplementary variables by putting "quanti.sup" and/or a list with the names of the variables which should be drawn |

`label` |
a list of character for the variables which are labelled (by default, all the drawn variables are labelled). You can label all the active variables by putting "var" and/or all the supplementary variables by putting "quanti.sup" and/or a list with the names of the variables which should be labelled |

`lim.cos2.var` |
value of the square cosinus under the variables are not drawn |

`cex` |
cf. function |

`title` |
string corresponding to the title of the graph you draw (by default NULL and a title is chosen) |

`new.plot` |
boolean, if TRUE, a new graphical device is created |

`...` |
further arguments passed to or from other methods |

Returns the variables factor map.
