R Statistical software for data visualization and data analysis, used by researchers, statisticians, & data miners for quantitative data analysis. Statistical Data Management and Analysis using R course provides an insight into quantitative data management and analysis (exploring, summarizing, statistical analyzing, visualizing). R is an open source software with many features for quantitative data management and analysis. Making Sense of Data is an important skill. Our modern world is a complicated place, and we are bombarded by data at every turn. The first step to understanding and making sense of data is being able to summarise data.

R is a programming language and software environment for statistical computing and graphics. The R language is widely used among statisticians and data miners for developing statistical data analysis. You will start with the most basic importing techniques and advanced ways to handle even the most difficult datasets to import. R has “become the de-facto standard for writing statistical software among statisticians. This course will give you a solid foundation in creating statistical analysis solutions using the R language, and how to carry out a range of commonly used analytical processes. Finally, you will learn to implementation and data analysis.
