# Scatterplot of two sets of Ct values from qPCR data.

### Description

Produces a plot of Ct values from two samples plotted against each other. Features can be marked based on for example feature class or type.

### Usage

1 |

### Arguments

`q` |
object of class qPCRset. |

`cards` |
vector, the two cards to plot against each other. |

`col` |
vector with the colour(s) to use for the points, or a character string ("type" or "class") indicating whether points should be coloured according to |

`pch` |
integer, the point type to use for the plot. |

`diag` |
logical, should the diagonal line y=x be plotted. |

`cor` |
logical, should information about the correlation between the two samples be included in the plot. The correlation is calculated both with and without removing Ct values above Ct.max. |

`Ct.max` |
numeric, all Ct values above this will be removed for calculating one of the correlations. |

`legend` |
logical, if |

`...` |
any other arguments are passed to |
