plot.lpda {lpda} | R Documentation |
Plot method for lpda classification
Description
plot.lpda
is applied to an lpda
class object. It shows a plot
in two dimensions with the distances to the computed hyperplane of each individual coloring each case with the real class.
Usage
## S3 method for class 'lpda'
plot(x, PCscores = FALSE, main = NULL, xlab = NULL, ylab = NULL,
col= NULL, pch = NULL, lty = NULL,
legend.pos = "topright",...)
Arguments
x |
Object of class inheriting from "lpda" |
PCscores |
Logical to show the first 2 PCscores. Only possible when PCA is applied. |
main |
An optional title for the plot. |
xlab |
An optional title for x-axis. |
ylab |
An optional title for y-axis. |
col |
An optional vector with colours for the groups. |
pch |
An integer specifying the symbol to be used in plotting points. When NULL, pch=20. |
lty |
The line type. If it is not specified, lty = 2 for the distances to the hiperplane and lty = 1 for PCs plot |
legend.pos |
The position for the legend. By default it is topright. NULL when no legend is required. |
... |
Other arguments passed. |
Value
Two dimensional plot representing the distances to the computed hyperplane of each individual colored with the real class.
