As we saw from functions like lm, predict, and others, R lets functions do most of the work. Contrast this to the LinearRegression class in Python, and the sample method on Dataframes. In terms of data analysis and data science, either approach works. r'' is a string with a backslash followed by the letter n. (Without the r it would be a newline.) b does stand for byte-string and is used in Python 3, where strings are Unicode by default.
