Beginning R: The Statistical Programming Language

آر R یک زبان برنامه ‌نویسی و محیط نرم ‌افزاری برای محاسبات آماری و تحلیل داده است که بر اساس زبان‌ های اس و اسکیم پیاده ‌سازی شده و به رایگان به زبان هاهی مختلف از جمله زبان فارسی (توسط دانشگاه فردوسی مشهد ترجمه شده) برای سیستم عامل های ویندوز، مک و انواع توزیع های لینوکس در دسترس است.

.

نرم افزار R دارای محدوده گسترده ‌ای از تکنیک ‌های آماری همچون: مدل‌ سازی خطی و غیرخطی، آزمون ‌های کلاسیک آماری، تحلیل سری ‌های زمانی، رده ‌بندی، خوشه ‌بندی و همچنین قابلیت‌ های گرافیکی است.

در محیط R، کدهای سی، سی پلاس پلاس و فورترن قابلیت اتصال و فراخوانی هنگام اجرای برنامه را دارند. این نرم افزار در محاسبات ماتریسی نیز کاربرد فراوانی دارد و در این زمینه، همپای نرم‌ افزارهایی ماننده اُکتاو و نسخه تجاری آن یعنی متلب است.

.

در این پست کتاب Beginning R: The Statistical Programming Language نوشته Dr. Mark Gardener را برای شما علاقه مندان به این نرم افزار R را آماده کرده ایم که در قالب 12 فصل و 507 صفحه به صورت PDF و به زبان انگلیسی ، آر را به طور کامل و جامع آموزش داده است. این کتاب در سراسر اینترنت کمیاب بوده و فقط برای فروش قرار داد که می توانید آن را با قیمت ناچیز ۵٫۰۰۰ تومان از سایت نوآوارن گرمی خریداری بفرمائید.
