دانلود کتاب تجزیه و تحلیل داده‌ها، بصری سازی، و مدل‌سازی داده در R 4

Welcome to Beginning Data Science in R 4. I wrote this book from a set of lecture notes for two classes I taught a few years back, “Data Science: Visualization and Analysis” and “Data Science: Software Development and Testing.” The book is written to fit the structure of these classes, where each class consists of seven weeks of lectures followed by project work. This means that the book’s first half consists of eight chapters with core material, where the first seven focus on data analysis and the eighth is an example of a data analysis project. The data analysis chapters are followed by seven chapters on developing reusable software for data science and then a second project that ties the software development chapters together. At the end of the book, you should have a good sense of what data science can be, both as a field covering analysis and developing new methods and reusable software products.
