SymPy is a Python library for symbolic computation. It provides computer algebra capabilities either as a standalone application, as a library to other applications, or live on the web as SymPy Live or SymPy Gamma.

R is primarily focused on statistical analysis and data visualization, making it ideal for data-centric tasks, while SymPy is tailored for symbolic mathematics and algebraic computations. Both have unique strengths, with R excelling in statistical modeling and SymPy in symbolic mathematics.
