plot.light_performance: Visualize Model Performance

Description

Minimal visualization of an object of class light_performance as geom_bar. The object returned has class ggplot and can be further customized.

Usage

# S3 method for light_performance
plot(x, swap_dim = FALSE,
  facet_scales = "free_y", rotate_x = FALSE, ...)

Arguments

An object of class light_performance.

swap_dim

Should representation of dimensions (either two "by" variables or one "by" variable and multiflashlight) of x aesthetic and dodge fill aesthetic be swapped? Default is FALSE.

facet_scales

Scales argument passed to facet_wrap.

rotate_x

Should x axis labels be rotated by 45 degrees? Default is FALSE.

...

Further arguments passed to geom_bar.

Value

An object of class ggplot2.

Details

The plot is organized as a bar plot as follows: For flashlights without "by" variable specified, a single bar is drawn. Otherwise, the "by" variable (or the flashlight label if there is no "by" variable) is represented by the "x" aesthetic. The flashlight label (in case of one "by" variable) is represented by dodged bars. This strategy makes sure that performance of different flashlights can be compared easiest. Set "swap_dim = TRUE" to revert the role of dodging and x aesthetic. Different metrics are always represented by facets.

Examples

Run this code

# NOT RUN {
fit_full <- lm(Sepal.Length ~ ., data = iris)
fit_part <- lm(Sepal.Length ~ Petal.Length, data = iris)
mod_full <- flashlight(model = fit_full, label = "full", data = iris, y = "Sepal.Length")
mod_part <- flashlight(model = fit_part, label = "part", data = iris, y = "Sepal.Length")
mods <- multiflashlight(list(mod_full, mod_part))
plot(light_performance(mod_full), fill = "darkred")
plot(light_performance(mod_full, by = "Species"), fill = "darkred")
plot(light_performance(mods))
plot(light_performance(mods, by = "Species"))
plot(light_performance(mods, by = "Species"), swap_dim = TRUE)
# }
