# LightGBM Analysis

Use this skill to build a LightGBM model on tabular data and export feature importance ranking results as both a table and a figure.

## Use This Skill When

- You need a command-line LightGBM workflow written in R.
- You need classification or regression on structured tabular data.
- You need ranked feature importance outputs for reporting or interpretation.
- You need standardized outputs under `table/`, `figure/`, and `data/`.

## Primary Command

```bash
Rscript scripts/main.R \
  --data_file <input_file> \
  --target_var <target_column> \
  --output_dir <output_dir>
```

## Prerequisites

- `Rscript` is available in the shell.
- Required R packages: `optparse`, `data.table`, `lightgbm`.
- Install basic dependencies with `Rscript -e 'install.packages(c("optparse", "data.table"), repos="https://cloud.r-project.org")'`.
- Install the R `lightgbm` package from the LightGBM project because it is usually not available from CRAN.
