آموزش برنامه نویسی R از مقدماتی تا پیشرفته

آر (R)، یک زبان برنامه‌نویسی و محیط نرم‌افزاری برای محاسبات آماری و تحلیل داده است که بر اساس زبان‌های اس و اسکیم پیاده‌سازی شده است. این نرم‌افزار متن باز، تحت اجازه‌نامه عمومی همگانی گنو عرضه شده و به رایگان قابل دسترس است. زبان اس بجز R، توسط شرکت Insightful، در نرم‌افزار تجاری اس‌پلاس نیز پیاده‌سازی شده است. اگرچه دستورات اس‌پلاس و R بسیار شبیه است اما این دو نرم‌افزار دارای هسته‌های متمایزی می باشند. R، حاوی محدوده گسترده‌ای از تکنیک‌های آماری (از جمله: مدل‌سازی خطی و غیرخطی، آزمون‌های کلاسیک آماری، تحلیل سری‌های زمانی، رده‌بندی، خوشه‌بندی و غیره) و قابلیت‌های گرافیکی است. در محیط R، کدهای سی، سی++ و فورترن قابلیت اتصال و فراخوانی هنگام اجرای برنامه را دارند و کاربران خبره می‌توانند توسط کدهای سی، مستقیماً اشیا R را تغییر دهند.

به درخواست دوستان دوره آموزش مقدماتی تا پیشرفته  برنامه نویسی به زبان R را برای شما آماده کردیم.

این دوره آموزشی محصول LiveLessons می باشد.

R Programming LiveLessons: Fundamentals to Advanced is a tour through the most important parts of R, the statistical programming language, from the very basics to complex modeling. It covers reading data, programming basics, visualization, data munging, regression, classification, clustering, modern machine learning and more.

About the Author:
Data scientist, Columbia University adjunct Professor, author and organizer of the New York Open Statistical Programming meetup Jared P. Lander presents the 20 percent of R functionality to accomplish 80 percent of most statistics needs. This video is based on the material in R for Everyone and is a condensed version of the course Mr. Lander teaches at Columbia. You start with simply installing R and setting up a productive work environment. You then learn the basics of data and programming using these skills to munge and prepare data for analysis. You then learn visualization, modeling and predicting and close with generating reports and websites and building R packages.
