R is the amazing, free, open-access software package for scientific graphs and calculations used by scientists worldwide. The R Student Companion is a student-oriented manual describing how to use R in high school and college science and mathematics courses. Written for beginners in scientific computation, the book assumes the reader has just some high school algebra and has no computer programming background. The author presents applications drawn from all sciences and social sciences and includes the most often used features of R in an appendix. In addition, each chapter provides a set of computational challenges: exercises in R calculations that are designed to be performed alone or in groups. Several of the chapters explore algebra concepts that are highly useful in scientific applications, such as quadratic equations, systems of linear equations, trigonometric functions, and exponential functions. Each chapter provides an instructional review of the algebra concept, followed by a hands-on guide to performing calculations and graphing in R. R is intuitive, even fun. Fantastic, publication-quality graphs of data, equations, or both can be produced with little effort. By integrating mathematical computation and scientific illustration early in a student’s development, R use can enhance one's understanding of even the most difficult scientific concepts. While R has gained a strong reputation as a package for statistical analysis, The R Student Companion approaches R more completely as a comprehensive tool for scientific computing and graphing.

R for Business Analytics looks at some of the most common tasks performed by business analysts and helps the user navigate the wealth of information in R and its 4000 packages. With this information the reader can select the packages that can help process the analytical tasks with minimum effort and maximum usefulness. The use of Graphical User Interfaces (GUI) is emphasized in this book to further cut down and bend the famous learning curve in learning R. This book is aimed to help you kick-start with analytics including chapters on data visualization, code examples on web analytics and social media analytics, clustering, regression models, text mining, data mining models and forecasting. The book tries to expose the reader to a breadth of business analytics topics without burying the user in needless depth. The included references and links allow the reader to pursue business analytics topics. This book is aimed at business analysts with basic programming skills for using R for Business Analytics. Note the scope of the book is neither statistical theory nor graduate level research for statistics, but rather it is for business analytics practitioners. Business analytics (BA) refers to the field of exploration and investigation of data generated by businesses. Business Intelligence (BI) is the seamless dissemination of information through the organization, which primarily involves business metrics both past and current for the use of decision support in businesses. Data Mining (DM) is the process of discovering new patterns from large data using algorithms and statistical methods. To differentiate between the three, BI is mostly current reports, BA is models to predict and strategize and DM matches patterns in big data. The R statistical software is the fastest growing analytics platform in the world, and is established in both academia and corporations for robustness, reliability and accuracy. The book utilizes Albert Einstein’s famous remarks on making things as simple as possible, but no simpler. This book will blow the last remaining doubts in your mind about using R in your business environment. Even non-technical users will enjoy the easy-to-use examples. The interviews with creators and corporate users of R make the book very readable. The author firmly believes Isaac Asimov was a better writer in spreading science than any textbook or journal author.

This book presents a wide array of methods applicable for reading data into R, and efficiently manipulating that data. In addition to the built-in functions, a number of readily available packages from CRAN (the Comprehensive R Archive Network) are also covered. All of the methods presented take advantage of the core features of R: vectorization, efficient use of subscripting, and the proper use of the varied functions in R that are provided for common data management tasks. Most experienced R users discover that, especially when working with large data sets, it may be helpful to use other programs, notably databases, in conjunction with R. Accordingly, the use of databases in R is covered in detail, along with methods for extracting data from spreadsheets and datasets created by other programs. Character manipulation, while sometimes overlooked within R, is also covered in detail, allowing problems that are traditionally solved by scripting languages to be carried out entirely within R. For users with experience in other languages, guidelines for the effective use of programming constructs like loops are provided. Since many statistical modeling and graphics functions need their data presented in a data frame, techniques for converting the output of commonly used functions to data frames are provided throughout the book.

The first Books of "IS", is full of contemplative designs and graftics, along with rhythmic writings. All are created to move gently, your sences, and your brain, to "stiring" you "awake", and into thinking, sensing and obseving the life within you and around you. The writings and graphics are meant to be contemplated upon, and carried into your daily life, so to awaken you to the truth of you and the universe of life here, now, and beyond "here" and the "now". I have also included pages at the end of each chapter for the reader's own inspired writings brought on by the repeated readings, and contemplations of the writings and graphics in this book, so to assist in the activation of your creative and intellectual mind: right and left brain functions. The Books of "IS" came about after my being mysteriously, intuitively guided, for over twenty-eight years, to write down messages of a higher conscious level, on truths of life, myself, and all life in general. The writings in BOOK ONE: The Dance of Becoming, are compiled writings from a higher presence of love that I was receiving, during a strong inter-sensing, to write down what was "calling" to me. This first began occuring during my pre-teens; then again as an adult, during times of great sorrow or/and lonliness. As an adult, and after writing for almost a year, the writings began taking on a deeper nature. They began to change into messages and memories of truth, guidance, and gentle love; coming forth, giving me more of the peace and joy they had been creating within me. The desire to write more "called" often and strongly, yet pleasantly to me; and the experience of it all was: ecstasy! I began to realize that I must have been touching down into deeper parts of myself, and then rising up to the higher parts of me: my Higher Soul! I was then feeling such peace, joy and knowing, that I no longer felt sadness nor lonliness; Instead I felt the great desire and joy to experience and to know more! It felt as if at these times I was my TRUE SELF! I felt complete and all knowing! I felt like I was with the Holies of Holies and the Angels! Then, in the year 1984, I was tellepathicly told by these Sacred Messengers of a higher power/Creator, to put all these writngs into books, and when the time came, publish them to aid all mankind, all existence. From these writings, I receive messages and teachings that went beyond mundane and into the higher planes of existence, connecting me with the Creator of all principles, of all life: There I connected with Holy Messengers of various kinds. I had asked for valadation on all this and soon found myself miraciously being lead to the meeting of those who were Guardians of these ancient, long protected Sacred Truths; along with findings in old books; and other similar occurences and people. These valadations ranged from old mystery schools, of various kinds, to ancient indigenous beliefs on creation, and a higher powerful being; to more modern religions and scientific findings. I also was lead in syn with others, who too, were receiving similar writings with same truths; some written a bit differently. In 1884, I was given the spiritual, tellepathic message, that in the future, I would be compiling these and other writings into books to be published for the world. This was so that many people could be reached more quickly, for the "quickening" had begun.They told me that the writings in this book and in others, were "seed-truths", selectively and rhythmicly placed; camouflaged, seeming at first, to those "not ready", as stories of meer fantasy, so called: "make-believe" and sci-fy. I was told the writings are done this way so to gently but powerfully, unlock the encoded truths within those who hear or read them and view the graphics.These writings therefore, are like camouflaged words/codes, "hidden" to many, but obvious to those who were ready :"remembering", "awakening"; therefore, protected from those who would abuse them and interput them with mis-understanding, in a negative way; thereby, creating too much chaos. The writings then, in the Books of "IS", are written in the forms of story, contemplative quotes, and poetic teachings, with various styles of poetry; delivering Knowledge, Wisdom and Understanding. This book's activational process is to assist in the "opening of the door" for: THOSE WHO SEEK TRUTH , AND SEEK THEMSELF. And, it is for: THOSE WHO ARE READY TO KNOW! That "door" opens to the All Knowing Universe of Truth, Wisdom, Knowledge and Understanding: THE KNOWING: The Supreme Intelligence: Book of Life/Records---The Memories of Truth! These writings then, are "seeds", hidden, yet not, to those who have or are, beginning to awaken and remember. "Seeds" of creation, hidden, yet there, awaiting: "THOSE WHO ARE READY..."
