Automated Statistical Analysis, Visualization, and Multi-Format Narrative Reporting in R

Overview
EasyStat bridges the gap between statistical output and actionable insight. A single function call delivers the statistical result, a plain-language narrative interpretation, and publication-ready tables, rendered in the RStudio Viewer, the R console, or Microsoft Word.
User-facing p-values are reported as percentages rounded to 4 decimal places, while raw model objects still retain the original numeric p-values for advanced use.
Installation
# From CRAN (when available)
install.packages("EasyStat")
# Development version from GitHub

Quick Start
library(EasyStat)
# Linear regression with narrative
easy_regression(mpg ~ wt + hp, data = mtcars)
# Logistic regression with odds ratios
easy_logistic_regression(am ~ mpg + wt, data = mtcars)
# t-test
easy_ttest(mpg ~ am, data = mtcars)
# One-way ANOVA
easy_anova(Sepal.Length ~ Species, data = iris)
# Descriptive statistics for multiple variables
easy_describe(mtcars, vars = c("mpg", "hp", "wt"))
# Correlation heatmap
easy_correlation_heatmap(mtcars, vars = c("mpg", "hp", "wt", "qsec", "drat"))
# Export any result to Word
result <- easy_logistic_regression(am ~ mpg + wt, data = mtcars)
export_to_word(result, file = "report.docx", title = "Transmission Model",

Four-Step Pipeline
| Step | Module | Role |
|---|---|---|
| 1 | Core Statistical Engine | Wraps lm(), glm(), t.test(), aov(), chisq.test(), var.test(), cor.test() |
| 2 | Metric Extractor | Uses model summaries and broom helpers to extract p-values, effect sizes, CIs, and fit metrics |
| 3 | Narrative Generator Module | Applies conditional logic to produce plain-language explanations |
| 4 | Unified Result Object | Returns easystat_result S3 objects with tables, narrative, and optional plots |
