Either plot projected data (if number is specified) or histogram of projection indices over all random starts

1 2 |

`x` |
PP3 object that you wish to plot. |

`number` |
If missing, then the plot information concerning all
of the project indices over all random starts
(using function |

`main` |
Argument for main title. |

`nbig` |
If plotting information on all indices, this argument controls the number of the largest projection indices and their identification number. |

`colvec` |
If plotting the projected data, you can supply a vector of colour indices to colour each observation in the plot |

`lab` |
As for |

`...` |
Other arguments to supply to the plot. |

This function can produce two types of plot. The first type, if
the `number`

argument is not supplied, produces a histogram
of projection index values (in black) and superimposes the
pseudo-index value density estimate, and median, upper quartile,
0.9 quantile and maximum values as vertical dotted lines.

If the `number`

argument is specified, it should be one of
the projection random start numbers and then the projected data
associated with that maximised projection index is plotted.
The points in the plot can be coloured (using `colvec`

) or
a text label supplied (using `lab`

) argument.
