## Introduction

**DrData** provides a point-and-click Shiny interface that covers the full
data science pipeline without writing a single line of R code.

## Launching the application

```{r eval=FALSE}
library(DrData)
run_app()
```

The browser opens automatically. Use the sidebar to navigate between modules.

## Workflow

1. **Data Import** — upload a CSV/Excel file or load `iris`, `mtcars`, or
   `Titanic` from the built-in examples.
2. **Preprocessing** — handle missing values, remove duplicates, scale
   numeric columns, and encode categorical variables.
3. **EDA** — explore distributions, correlations, and run normality tests
   with interactive Plotly charts.
4. **Regression** — choose from 8 algorithms, tune hyperparameters, view
   metrics (RMSE, MAE, R², Adj-R², MAPE, AIC, BIC), and inspect diagnostic
   plots including interaction effect visualisations.
5. **Classification** — train classifiers, evaluate with ROC curve and
   confusion matrix, and inspect variable importance.
6. **Clustering** — run K-Means, Hierarchical, or DBSCAN clustering, then
   visualise results with elbow plots, silhouette analysis, and cluster
   profiles.
