Function to plot the probabilities to belong to a certain class in binary classification problems. These probabilities are often calculated using a logistic regression model. The class membership of the samples is displayed using a colored strip (with legend below the plot).

`proportions` |
A vector containing the calculated probabilities to belong to a certain class in binary classification problems. These probabilities are often calculated using a logistic regression model. |

`classVar` |
A vector containing the class where the sample belongs to |

`sampleNames` |
A vector with the names of the samples |

`plot` |
logical. If |

`barPlot` |
Should a barplot be drawn ( |

`layout` |
boolean indicating whether |

`main` |
Main title for the scores plot; if not supplied, 'Scores Plot' is used as a default |

`sub` |
Subtitle for the scores plot; if not supplied, the classification technique and the chosen number of features are displayed |

`...` |
Additional graphical parameters to pass to the plot function |
