Getting Started with EDAForge

Introduction

EDAForge is an R package for automated exploratory data analysis (EDA). It provides functions for descriptive statistics, missing value analysis, correlation analysis, visualization, outlier detection and automated reporting.

library(EDAForge)

Example dataset

This vignette uses the built-in iris dataset.

data <- iris
head(iris)
#>   Sepal.Length Sepal.Width Petal.Length Petal.Width Species
#> 1          5.1         3.5          1.4         0.2  setosa
#> 2          4.9         3.0          1.4         0.2  setosa
#> 3          4.7         3.2          1.3         0.2  setosa
#> 4          4.6         3.1          1.5         0.2  setosa
#> 5          5.0         3.6          1.4         0.2  setosa
#> 6          5.4         3.9          1.7         0.4  setosa

Numeric summary

Generate descriptive statistics for all numeric variables.

num_sum <- numeric_summary(iris)

#> Petal.Width         0.818      -0.366        0.963       1.000

Export numeric summary

Output files in examples and vignettes should always be written to a temporary directory.

outfile <- file.path(tempdir(), "NumericSummary.csv")

export_numeric_summary(
  num_sum,
  outfile
)

file.exists(outfile)
#> [1] TRUE
