Hi everyone, welcome to the course. This is the introduction to R course at Ewha Womans University.
R is a great programming language for statistical analysis and data science. I hope you enjoy R in this course and find many useful applications for your own field.
This course is designed for students who don’t have any programming background in social science.
In this lecture note, this font represents R commands, variable names, and package names.
In order to maximize your learning in this semester, you should read the weekly reading assignment in our textbook, R for Data Science.
If you have any question on this lecture (e.g., errors in running R, questions about quiz), please send your questions to r.ewha.questions.2021@gmail.com. Then, Iand TA(Teaching Assistant) will answer your questions.
In this lecture notes, I will include interactive code chunks provided by DataCamp that will allow you to actually run and practice R codes within this lecture notes. Please type 3+4 and click Run button to ask R to calculate the expression.
