Plot Methods for ROC and CAC Objects

plot() methods for the objects returned by the ROC and CAC functions, so that plot(x) works directly rather than requiring the user to know which plot builder matches which object.

Usage

# S3 method for class 'lineup_roc_data'
plot(x, ...)

# S3 method for class 'lineup_roc'
plot(x, ...)

# S3 method for class 'lineup_cac_data'
plot(x, ...)

# S3 method for class 'lineup_cac'
plot(x, ...)

# S3 method for class 'lineup_fullroc_data'
plot(x, ...)

# S3 method for class 'lineup_fullroc'
plot(x, ...)

Arguments

x

An object returned by one of the ROC or CAC functions listed above.

...

Additional arguments passed to the underlying plot builder.

Value

A ggplot2 object.

Details

Each ROC/CAC analysis comes in two forms. The *_data() function computes and returns the data only; the function without the suffix wraps it, builds the plot, and returns a classed object with the plot stored in $plot:

• make_rocdata / make_roc

• make_cacdata / make_cac

• make_fullroc_data / make_fullroc

These methods accept either form. When a plot has already been built it is returned as-is; otherwise it is constructed with the matching builder (make_roc_gg, make_cac_gg or plot_fullroc).

The value is an ordinary ggplot object, so it can be modified with the usual + syntax, e.g. plot(x) + ggplot2::theme_minimal().

Examples

data(lineup_example)
plot(make_rocdata(lineup_example))

plot(make_cacdata(lineup_example))
