This paper presents a strategy to bridge the gap between statistical methodologists and end-users by using R as the computational back-end and Python for the graphical user interface (GUI). The proposed approach allows methodologists to implement new statistical methods in R, which are then automatically integrated into the GUI for use by non-technical end-users. This is achieved through a software architecture where an agnostic front-end GUI (in Python) interfaces with a calculation and graphics engine (in R), using simple standards. The GUI is agnostic in that it can render inputs to and results from arbitrary routines implemented in the calculation engine, as long as they conform to predefined standards. This architecture allows for a 'two-tiered' distribution of statistical methods: advanced users can use the underlying R package directly, while non-technical users can use the GUI without knowing that R is the back-end. The paper uses meta-analysis as an example to illustrate the proposed strategy. Meta-analysis is a quantitative synthesis of information from independent sources, often used to answer questions that individual studies are underpowered to address. However, practitioners often rely on GUI-driven tools that lag behind the latest statistical methods. The proposed solution is an open-source meta-analysis software called OpenMeta-Analyst, which uses R as the statistical engine and Python for the GUI. This software allows methodologists to implement new methods in R, which are then automatically integrated into the GUI for use by end-users. The paper also discusses the benefits of using R and Python for this purpose. R is well-suited for statistical programming due to its mathematical expressiveness, large number of existing libraries, and active developer community. Python is ideal for implementing a GUI due to its cross-platform nature, large open-source community, and the rpy library, which facilitates communication with R. The proposed architecture allows for the development of a user-friendly interface while leveraging the latest advanced statistical methods implemented by methodologists. The paper concludes that this approach is not limited to meta-analysis and could be applied to other mathematically driven application areas where non-technical users need to access advanced statistical methods.This paper presents a strategy to bridge the gap between statistical methodologists and end-users by using R as the computational back-end and Python for the graphical user interface (GUI).
