Start with the required libraries, and then load some data.

Code

# data manipulation
library(tidyverse)
library(janitor)

# Data Exploration
library(ppsr)
library(correlationfunnel)
library(DataExplorer)

# Visualisation addition
library(plotly)


# Load Data ----
promotions_tbl <- readr::read_csv(file = "train.csv") %>% 
    janitor::clean_names()

# reduce the dataset size
cleaned_promotions_tbl <-
promotions_tbl %>%
    tidyr::drop_na() %>% 
    dplyr::mutate(
        is_promoted = as.character(is_promoted),
        is_promoted = if_else(is_promoted==1, "Yes", "No") %>% as.factor()
    )

1. Predictive Power Score

Code

cleaned_promotions_tbl %>%
    select(-employee_id) %>%
    visualize_pps(
        y = 'is_promoted', 
        do_parallel = FALSE
        )

2. Correlation Funnel

Code

cleaned_promotions_tbl %>% 
    select(-employee_id) %>% 
    binarize() %>% 
    correlate(target = is_promoted__Yes) %>% 
    plot_correlation_funnel(interactive = TRUE) %>% 
    plotly::config(displayModeBar = FALSE)

3. DataExplorer

Default Heatmap

Code

corr_plot <- cleaned_promotions_tbl %>% 
    select(-employee_id) %>% 
    DataExplorer::plot_correlation(
        theme_config = list(
            legend.position = "none",
            axis.text.x     = element_text(angle = 90)
                )
    )

Interactive Heatmap

Code

corr_plot$data$value <- round(corr_plot$data$value, digits = 2)

plotly::plotly_build(corr_plot) %>% 
    plotly::layout(width = 700, height = 700) %>% 
    plotly::config(displayModeBar = FALSE)
