# Plot 1D graph of results from between group analysis

### Description

Plots a 1D graph, of results of between group analysis similar to that in Culhane et al., 2002.

### Usage

1 |

### Arguments

`x` |
Object of the class |

`ax` |
Numeric. The column number of principal component (\$ls and \$li) to be used. Default is 1. This is the first component of the analysis. |

`cols` |
Vector of colours. By default colours are obtained
using |

`hor` |
Logical, indicating whether the graph should be plotted horizontally or vertically. The default is a horizontal plot. |

`scaled` |
Logical, indicating whether the coordinates in the graph should be scaled to fit optimally in plot. Default is TRUE |

`centnames` |
A vector of variables labels. Default is NULL, if NULL the row names of the centroid \$li coordinates will be used. |

`varnames` |
A vector of variables labels. Default is NULL, if NULL the row names of the variable \$ls coordinates will be used. |

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

### Details

This will produce a figure similar to Figure 1 in the paper by Culhane et al., 2002.

`between.graph`

requires both samples and centroid co-ordinates (\$ls, \$li) which are passed
to it via an object of class `bga`

. If cases are to be coloured by class, it also requires
a \$fac `factor`

which is also passed to it via an object of class `bga`

.

To plot a 1D graph from other multivariate analysis such as PCA (`dudi.pca`

),
COA (`dudi.coa`

), or `coinertia`

analysis. Please
use `graph1D`

.
