This book introduces readers to the fundamentals of creating presentation graphics using R, based on 100 detailed and complete scripts. It shows how bar and column charts, population pyramids, Lorenz curves, box plots, scatter plots, time series, radial polygons, Gantt charts, heat maps, bump charts, mosaic and balloon charts, and a series of different thematic map types can be created using R’s Base Graphics System. Every example uses real data and includes step-by-step explanations of the figures and their programming. The open source software R is an established standard and a powerful tool for various visualizing applications, integrating nearly all technologies relevant for data visualization. The basic software, enhanced by more than 7000 extension packs currently freely available, is intensively used by organizations including Google, Facebook and the CIA. The book serves as a comprehensive reference guide to a broad variety of applications in various fields. This book is intended for all kinds of R users, ranging from experts, for whom especially the example codes are particularly useful, to beginners, who will find the finished graphics most helpful in learning what R can actually deliver.
After 7 years of clinical use, percutaneous transluminal coronary angio plasty (PTCA) has now found worldwide acceptance, and its basic techniques are well standardized. A growing number of invasive cardi ologists are acquainting themselves with the procedure in order to be in a position to offer new therapeutic options to their patients. However, the transition from the diagnostic to the therapeutic intervention is not always easily accomplished. Certain prerequisites concerning technique, the physician, technical equipment, and program organization are necessary for safe and effective performance. The consequences of unsuccessful coronary angioplasty range from waste of time and money to severe complications for the patient; the decision to perform PTCA needs to be based on sound indications and techniques according to the best current scientific evidence. Techniques and technology for coronary angioplasty continue to evolve. Scientific evidence of its short-and long-term value continues to accumulate, and applications of the procedure are still being extended. This volume is obviously no substitute for well-guided hands-on experience with the procedure; it is intended rather to present current policies of patient selection and patient management; to describe standard techniques (femoral and brachial approaches) and potential applications; to point out problem areas and limitations of the proce dure; and to provide tips that may be useful even for the more experienced angioplasty operator.
Current knowledge concerning both morphological and functional cryptorchid-related alterations in the various testicular compartments is summarized in this valuable new publication. Damage to the germinal epithelium and resulting infertility in both humans and experimental animals as well as the degree of damage to the different stages of germ cell development is discussed. In addition, information concerning hormonal therapy and orchidopexy to reverse cryptorchid-related damage is provided. Morphological alterations in Sertoli and Leydig cells is discussed in terms of cellular hypertrophy and hyperplasia, alterations in organelle number and characteristics as well as changes in cell-cell junctional complexes. Changes in Sertoli cell and Leydig cell function, including gonadotropin binding, steroidogenesis and other metabolic alterations is also outlined,as well as the influence of altered testicular function on subsequent hypothalamic-pituitary changes. Vascular disruption, the potential role of paracrine substances and direct thermal damage, all of which may be responsible for the resulting detrimental changes in one or more testicular compartments, are considered.
