Explain
R-Quant packages provide prebuilt functions for finance, statistics, and data analysis, reducing the need to implement complex algorithms from scratch.
They include packages for time series analysis, portfolio optimization, risk management, and derivative pricing.
Users can integrate them with other R packages for data visualization, machine learning, and reporting.
Widely used in finance, economics, and quantitative research for reproducible and automated analysis.
Commonly accessed via CRAN, GitHub, or internal organizational repositories.
