RQuantlib


"Quant" is short for quantitative analyst. Those people are supposed to be the "brains behind financial models", and are usually with advanced degrees in disciplines such as physics, mathematics and computer science.

QuantLib is a free and widely used library of financial models written in C++ for quants or those who are interested in quant work. Though QuantLib has been the most popular open source computational tool for quants, it seems too painful for a starter who just learned Black-Scholes formula to get the price of the most common financial instrument, call option, using QuantLib.

RQuantLib connects the well-written QuantLib library to GNU R. With RQuantLib, You do not have to know C++ programming to get an option price anymore. Instead, it’s just one command if you installed RQuantLib. What’s more, you could skip all the overwhelming steps of compiling and avoid the risk of being bogged down by compiling bugs. RQuantLib will help you study many financial models without requiring you as a veteran in C++. Also, in business, this means it could save you the cost of training people or build a fast and accurate computational tool.
