### Description

Plot log-ratios/log-intensities for all unique pairs of data vectors.

### Usage

1 2 3 |

### Arguments

`X` |
NxK |

`Alab,Mlab` |
Labels on the x and y axes. |

`Alim,Mlim` |
Plot range on the A and M axes. |

`pch` |
Plot symbol used. |

`...` |
Additional arguments accepted by |

`add` |
If |

### Details

Log-ratios and log-intensities are calculated for each neighboring pair of channels (columns) and plotted. Thus, in total there will be K-1 data set plotted.

The colors used for the plotted pairs are 1, 2, and so on. To change the colors, use a different color palette.
