Description
Book SynopsisDrawing on Gregg Hartvigsen’s extensive experience teaching biostatistics and modeling biological systems, this text is an engaging, practical, and lab-oriented introduction to R for students in the life sciences.
Trade ReviewAn excellent, easy-to-read introduction to biostatistics and the software program R. Simple but rigorous, with top-notch coverage of R. I would recommend this book to both colleagues and students. -- Andy Conway, Princeton University A recommendation for any college-level course strong in biostatistics and modeling...a fine guide for science and R programming students alike. Midwest Book Review Hartvigsen has succeeded in accomplishing his stated objectives. Buy the book and share the knowledge with students... the book is relevant, timely, and just what is needed with current trends in science education. Ecology A well-written overview of both biostatistics and R programming... this volume will fill an important niche for undergraduate biology. Quarterly Review of Biology
