plot.pps: Visualize Information for an "pps" Object

Description

Visualize by attribute of `pps` class. The plot of a PPS(Predictive Power Score) is a bar plot or tile plot by PPS.

Usage

# S3 method for pps
plot(x, typographic = TRUE, base_family = NULL, ...)

Value

A ggplot2 object.

Arguments

x: an object of class "pps", usually, a result of a call to pps().
typographic: logical. Whether to apply focuses on typographic elements to ggplot2 visualization. The default is TRUE. if TRUE provides a base theme that focuses on typographic elements using hrbrthemes package.
base_family: character. The name of the base font family to use for the visualization. If not specified, the font defined in dlookr is applied. (See details)
...: arguments to be passed to methods, such as graphical parameters (see par).

Details

The base_family is selected from "Roboto Condensed", "Liberation Sans Narrow", "NanumSquare", "Noto Sans Korean". If you want to use a different font, use it after loading the Google font with import_google_font().

Examples

Run this code

library(dplyr)

# If you want to use this feature, you need to install the 'ppsr' package.
if (!requireNamespace("ppsr", quietly = TRUE)) {
  cat("If you want to use this feature, you need to install the 'ppsr' package.\n")
}

# pps type is generic ======================================
pps_generic <- pps(iris)
pps_generic

if (!is.null(pps_generic)) {
  # visualize pps class 
  plot(pps_generic)
}

# pps type is target_by =====================================
##-----------------------------------------------------------
# If the target variable is a categorical variable
# Using dplyr
pps_cat <- iris %>% 
  target_by(Species) %>% 
  pps()

if (!is.null(pps_cat)) {
  # plot pps class
  plot(pps_cat)
}

##---------------------------------------------------
# If the target variable is a numerical variable
# Using dplyr
pps_num <- iris %>% 
  target_by(Petal.Length) %>% 
  pps()

if (!is.null(pps_num)) {
  # plot pps class
  plot(pps_num)
}
