R-Tips Weekly

This article is part of R-Tips Weekly, a weekly video tutorial that shows you step-by-step how to do common R coding tasks. Pretty cool, right?

Here are the links to get set up. 👇

This Tutorial is Available in Video (12-minutes)

I have a 12-minute video that walks you through these top 10 R packages for EDA and how to use them in R. (These are the ones I use most commonly) 👇

Importance of Exploratory Data Analysis

Exploratory Data Analysis (EDA) is a crucial step in any data science project. It helps you understand the underlying structure of your data, identify patterns, detect anomalies, and test hypotheses. EDA enables you to make informed decisions about data cleaning, feature selection, and model selection.

Top 10 R Packages for EDA

To make your EDA process more efficient and insightful, here are the top 10 R packages you should know. Get the R code and dataset so you can follow along here.

Setup the EDA Packages and Dataset in R:

First, make sure you install all of the R packages I’ll be demo-ing today. Then load the data set I’ll be using so you can reproduce the results. Run this code:

4. PerformanceAnalytics: Correlation Matrix with Scatterplots and Histograms

PerformanceAnalytics provides advanced charts and statistical functions for financial analysis (I actually use PerformanceAnalytics inside my tidyquant package for easier financial analysis). But, most people have no idea it has an amazing chart.Correlation() function that is fast and awesome. Run this code:

5. GGally: Scatterplot Matrix with Pairwise Relationships

GGally extends ggplot2 by adding several functions to reduce the complexity of combining geometric objects. The ggpairs() function is one of my favorite functions for assessing Pairwise Relationships. So powerful. Run this code:

Bonus: Five (5) Underrated EDA Libraries in R:

I had to call it quits at 10. But here are 4 more up and coming EDA libraries that are underrated:

  1. Radiant: A shiny app for creating reproducible business and data analytics reports. Get my radiant deep dive here.

  2. Correlationfunnel: I use this R package all the time for quick correlation anlaysis and detecting critical relationships. Full Disclosure: I authored this R package. (Get the introduction here.)

  3. GWalkr: Like Tableau in R for $0. Get my GWalkR deep-dive here.

  4. Esquisse: Also like Tableau in R for $0. Get my Esquisse deep-dive here.

  5. Explore: A simple shiny app for quickly exploring data. Get my explore deep-dive here.
