This method defines the plotting behavior for objects of the class brplPlot. It generates a
scatter plot visualizing the relationship between two variables (var1 and var2) along with
classification indicators and an additional line for further insights.
# S4 method for brplPlot
plot(x, y, ...)This function does not return a value. It generates a plot as a side effect.
An object of class brplPlot. The object must include the following slots:
@data: A data frame containing the data to be plotted, including var1, var2,
and a classification indicator indicator.
@var1: A string specifying the name of the first variable to be plotted (X-axis).
@var2: A string specifying the name of the second variable to be plotted (Y-axis).
@indicator: A binary variable indicating the classification or grouping of points.
@tau: A threshold value included in the plot's title.
@plvar2: A matrix object defining the data points for the additional line in the plot.
Ignored. Included for compatibility with the generic plot function.
Additional arguments passed to the base R plot function.
This method creates:
A scatter plot with points colored based on the value of indicator:
darkgreen for indicator = 1.
blue for other values.
An additional line, derived from the plvar2 matrix, drawn in black.
The title of the plot includes the threshold value (tau) for easier interpretation.
