If you're a biomedical student or serious scientist, you'll have to perform some pretty complex linear and non-linear calculations. R-Project is an analytical tool designed to provide a wide variety of statistical analysis for researchers in statistical methodology. It offers features such as linear and non-linear modeling, classical statistical tests, time-series analysis, classification, clustering methods, and graphical techniques. The program excels in producing high-quality plots with mathematical symbols and formulas. While it puts control in the hands of the user, it requires a deep understanding of complex tools to truly benefit from it. Being open source, it allows for customization by users through easy access to the source code.
R-Project is a professional analytical tool strictly for experienced or PhD level scientists. Beginners should steer clear due to the lack of instructions tailored for them.
