The course is aimed at students interested in programming language and environment R and the field of data science as well, as R is widely used for data science applications. R is not only a programming language designed for statistical computing and graphics purposes, but also a Turing-complete general-purpose programming language suitable for complex tasks solutions. Advantages of R over commercial systems such as MATLAB are (i) open-source distribution ? both free in the sense of costing no money (?free-as-in-beer?) and having absolutely no restrictions on source code editing or commercial use (?free-as-in-speech?). Among other benefits, (ii) there is a large online community congregated around R ready to help and answer user?s questions; R also provides (iii) an easy development of R web applications or (iv) user-friendly TeX documents typesetting directly via R code. The syntax of R language is simple, intuitive and quite similar to the syntax of MATLAB language. According to the recent kaggle.com worldwide statistics, R became the most popular programming language chosen for data analysis, data science and machine learning. Let?s say R is the lingua franca of data science. Class is practise-based and focused on problem-solving, number-crunching exercises and on real-data analyses solved via hands-on R programming and scripting; assigned tasks follow an easy-to-difficult schedule.


The course has no formal prerequisites. No prior experience with R is necessary, although some familiarity with procedural or even scripting programming languages such as MATLAB, Octave or Python would be helpful.
