Welcome to the world of interactive data analysis! Today, we’re diving into how to use the ExPanDaR package in R. This handy tool makes exploring your data as easy as pie, providing a Shiny-based app that allows you to analyze data quickly and effectively. Whether you’re a researcher or a student, ExPanDaR is here to streamline your exploratory data analysis (EDA) workflow. Let’s roll up our sleeves and get started!

What is ExPanDaR?

ExPanDaR stands for “Explore Panel Data with R.” It’s a package designed to facilitate interactive exploratory data analysis through a web-based app. Think of it as your personalized analysis assistant that not only helps you visualize data but also allows you to download R notebook code reflecting your analysis. It addresses two main needs:

• Providing a toolbox for on-the-fly exploration of data.
• Allowing users to assess the robustness of empirical evidence without direct access to underlying data.

Installing ExPanDaR

To start utilizing ExPanDaR, you need to install the package in R. Here’s how:

install.packages("ExPanDaR")

library(ExPanDaR)

If you’re keen to test the latest development version, follow these steps:

if (!require(devtools)) install.packages("devtools")

devtools::install_github("joachim-gassen/ExPanDaR")

library(ExPanDaR)

How to Use ExPanD

Now, let’s kick off exploring with ExPanD! You can start the application with or without any arguments:

rExPanD()  # Starts with an upload dialog

Or explore a pre-loaded dataset:

rExPanD(mtcars)  # Use mtcars dataset

For more comprehensive use, including long-format panel data, here’s how you proceed:

rExPanD(df = worldbank, 
                  df_def = worldbank_data_def, 
                  var_def = worldbank_var_def, 
                  df_name = "World Bank Data", 
                  config_list = ExPanD_config_worldbank, 
                  export_nb_option = TRUE)

Consider it like baking a cake; you gather your ingredients (data), mix them (analyze), and finally, you can take your delicious cake (analysis results) with you as a recipe (notebook)!

Utilizing ExPanDaR Functions

The fun doesn’t stop there! ExPanDaR comes packed with functions ideal for enhancing your EDA workflow. These functions allow you to create standard tables and plots quickly. For detailed guidance, check out this vignette.
