Introduction to R
R is a language build up with symbols, rules and functions. The objects in R are vectors and matrices. A typical data frame is a special matrix that consists of rows (e.g. individuals) and columns (e.g. variables), and has the variable names on top of the columns. The summary shows how to use functions, the overview is a list of R commands, and I give the solutions to the exercises and the IMDB dataset which you can download.
