Beginning Using R For Data Analysis

A first course for learning R programming

What you'll learn
Hope this course will provide you the greatest possibility to build foundations of R language, such that you can apply it effectively to your own data tasks.
You will be skillful with core concepts and basic data management methods in R, e.g. data structures, variables, sorting, merging, subsetting datasets.
You will get enough knovledge in plotting statistical graphs in R, using ggplot2 package in particular.
You will get touch with some addvanced data management methods in R, e.g. writing functions, using control flow, working with strings, reshaping datasets, etc.
You will be able to get started working with basic statistical and data analysis in R.
Requirements
No programming experience is needed, at least you can operating your computer in Windows.
Knowledge of statistics in elementary level is a prerequisite, e.g. mean, standard deviation, correlation, etc.
Description
R is one of the most popular programming languages and framework for statistical computing and data science application currently available. The goal of this course is to bring you up to start this comprehensive software as quickly as possible, such that you can apply it effectively to your own data analysis.This course is built for people of any age who trie to start programming in R at first time or even have never programmed at all. If you want to learn the basics of programming quickly so you can focus on interesting projects, and you like to test yourunderstanding of new concepts by solving meaningful problems, then this course is appropriate for you.The course contents are divided into five main sections. The first section -Get started with R environmentprovides a brief overview of R programming language as well as the installation of R and RStudio, so will make you become familiar with the R environment.Section 2 - R data structure and datasetcovers mainly the basics of R data structure, and how to import data files to create useful format for further analysis in R.Section 3 provides a brief overview of some useful basic data management methods in R, which includes mainly data type conversions,recoding variables, handling dates and missing values, Selecting and dropping variables, Sorting, merging, and subsetting datasets.Section 4, some of the more addvanced data management methods in R are explained. The main topics in this section include mathematical and statistical functions, functions for string and character, control flow in R, writing your own functions, and reshaping and aggregating datasets as well as summary statistics. R graphics is covered in section 5. In this section, we will introduce the ggplot2 package, and how to creat some simple bivariate (two-variable) graphs, as well as using grouping and faceting to create multivariate graphs, how to save graphs in multiple formats, and how to plot some basic statistical plots.Several virtual datasets suitable for R framework are followed during the course.Each section has its own source code file written in R-format, which can be loaded into RStudio. you can download the source files from the course page.By the end of the course you will be given an exercise which you can utilize all the knowledge learned to practice and evalutate what you have learned in this course.
