# 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
