Abstract
R is a programming language and environment which is mainly aimed to be used for statistical calculations and data analysis. Since a vast amount of human resource is consumed for its source code and packages; it is comprehensive, large in size and more common among others. Extending computer software with statistical calculation routines requires extra human resource, therefore, the need of wrapper libraries has been appeared. There are many software libraries that communicate R with other languages. Despite they render similar services, they have their own pros and cons. RCaller is a software library which comes into prominence with its simplicity. In this paper we introduce the library with some examples. We mention its abilities as well as its limitations. RCaller can be used in relatively small projects as it has painless start-up process and steep learning curve.
