July 6 2015 was one of the starting dates for the Data Scientist’s Toolbox course, taught by Prof. Jeff Leek of Johns Hopkins’ University. This course is an introductory overview of the other courses of Johns Hopkins’ Data Science Specialization available on Coursera. There are several interesting aspects in this specialization among which the use of R as the main tool to perform data analysis and manipulation and I am quite excited as until now in my Data Science adventure I have only used Python and C++ (in the two courses From University of Illinois Urbana Champaign: “Text Retrieval and Search Engines” and “Text Mining and Analytics”). This course does not actually teach R, but it tells you how to install the language, the main tool (RStudio) and how to install and load modules. The next course in the specialization is about the R programming language. One very positive aspect of these courses is that they are repeated monthly, so there are dates already available for the next months until December 2015.
