`x` |
An object of class |

`which` |
Integer in 1:5; the particular variant(s) of plot required.
A vector is permitted, in which case plots are produced in ascending order
of |

`main` |
Main title for the plot |

`ask` |
logical; if 'TRUE', the user is _ask_ed before each plot, see 'par("ask=")' |

`caption` |
A list of captions for |

`xlab` |
x-axis label, currently passed only to the histogram plot. |

`...` |
Additional parameters passed to other functions. See details for which parameters are passed. |

`cex.caption` |
Expansion factor for individual plot captions; as |

`cex.main` |
Expansion factor for main title; as |

`lwd.y, col.y, lty.y` |
Line width and colour for the location line in the histogram and density plots. Setting lwd.y=0 suppresses the location line. |

`col.qqline, lty.qqline, lwd.qqline` |
Graphical parameters for the Q-Q line in the Q-Q plot. |

For uncert objects created with methods other than MC, the plot types are:

`which=1`

A histogram of the MC replicates in

`x$MC$y`

, with optional line for`x$MC$y`

. The histogram is produced using`hist.default`

`which=2`

A Q-Q plot of the MC replicates in

`x$MC$y`

, with Q-Q line. The plot uses`qqnorm.default`

. If`datax`

is not present (in sQuote...), it is set to`TRUE`

.`which=3`

A density plot of the MC replicates in

`x$MC$y`

. The plot calls`density.default`

to calculate the density and`plot.density`

to produce the plot.`which=4`

A bar plot of eqncor(x_i,y) if

`x$y`

is present. Any correlation method supported by`stats::cor`

may be included in ‘...’ (e.g as`method="pearson"`

.`which=5`

A bar plot of eqncov(x_i,y) if

`x$y`

is present. Any correlation method supported by`stats::cov`

may be included in ‘...’ (e.g as`method="pearson"`

.

Values outside 1:5 are silently ignored.

Parameters in ‘...’ are passed to the various plot methods or calculations called. Only those parameters relevant to a given plot are passed to each calculation or plotting function, so ‘...’ can include any parameter accepted by any of the functions called.

For the x-y correlation and x-y covariance plot, values in `x$cor.xy`

are
used if available. If not, `stats::cor`

or `stats::cov`

is called on values
in `x$MC$y`

and `x$MC$x`

if the latter is available
(i.e. `uncertMC`

was called with `keep.x=TRUE`

). If neither
`x$cor.xy`

nor `x$MC$x`

is present, or if `method`

is
unknown, the plot is skipped with a warning.

`plot.uncertMC`

invisibly returns `NULL`

.

None.
