Arguments

x

An R object.

...

Further graphical parameters.

axes

A length-two numeric vector giving the dimensions to be plotted.

labels

A logical scalar: should labels be drawn? Labeling a large number of points can be computationally expensive and make the graph difficult to read. A selection of points to label can be provided using a list of two named elements, filter (a string specifying how to filter the labels to be drawn) and n (an integer specifying the number of labels to be drawn). See examples below.

extra_quali

An optional vector of qualitative data for aesthetics mapping.

extra_quanti

An optional vector of quantitative data for aesthetics mapping. If a single character string is passed, it must be one of "observation", "mass", "sum", "contribution" or "cos2" (see augment()).

color

The colors for lines and points (will be mapped to extra_quanti or extra_quali; if both are set, the latter has priority). Ignored if set to FALSE. If NULL, the default color scheme will be used.

fill

The background colors for points (will be mapped to extra_quanti or extra_quali; if both are set, the latter has priority). Ignored if set to FALSE.

symbol

A vector of plotting characters or symbols (will be mapped to extra_quali). This can either be a single character or an integer code for one of a set of graphics symbols. If symbol is a named a named vector, then the symbols will be associated with their name within extra_quali. Ignored if set to FALSE.

size

A length-two numeric vector giving range of possible sizes (greater than 0; will be mapped to extra_quanti). Ignored if set to FALSE.

xlim

A length-two numeric vector giving the x limits of the plot. The default value, NULL, indicates that the range of the finite values to be plotted should be used.

ylim

A length-two numeric vector giving the y limits of the plot. The default value, NULL, indicates that the range of the finite values to be plotted should be used.

main

A character string giving a main title for the plot.

sub

A character string giving a subtitle for the plot.

ann

A logical scalar: should the default annotation (title and x and y axis labels) appear on the plot?

frame.plot

A logical scalar: should a box be drawn around the plot?

panel.first

An expression to be evaluated after the plot axes are set up but before any plotting takes place. This can be useful for drawing background grids.

panel.last

An expression to be evaluated after plotting has taken place but before the axes, title and box are added.
