plot.lda | R Documentation |

Plots a set of data on one, two or more linear discriminants.

```
## S3 method for class 'lda'
plot(x, panel = panel.lda, ..., cex = 0.7, dimen,
abbrev = FALSE, xlab = "LD1", ylab = "LD2")
```

`x` |
An object of class |

`panel` |
the panel function used to plot the data. |

`...` |
additional arguments to |

`cex` |
graphics parameter |

`dimen` |
The number of linear discriminants to be used for the plot; if this
exceeds the number determined by |

`abbrev` |
whether the group labels are abbreviated on the plots. If |

`xlab` |
label for the x axis |

`ylab` |
label for the y axis |

This function is a method for the generic function
`plot()`

for class `"lda"`

.
It can be invoked by calling `plot(x)`

for an
object `x`

of the appropriate class, or directly by
calling `plot.lda(x)`

regardless of the
class of the object.

The behaviour is determined by the value of `dimen`

. For
`dimen > 2`

, a `pairs`

plot is used. For `dimen = 2`

, an
equiscaled scatter plot is drawn. For `dimen = 1`

, a set of
histograms or density plots are drawn. Use argument `type`

to
match `"histogram"`

or `"density"`

or `"both"`

.
