Project Description(Last Updated On: November 12, 2017)
Character strings can turn up in all stages of a data science project. One might have to clean messy string input before analysis, extract data that is embedded in text, or automatically turn numeric results into a sentence to include in a report. Perhaps the strings themselves are the data of interest, and one needs to detect and match patterns within them. This course helps the student master these tasks by teaching how to pull strings apart, put them back together, and use stringr to detect, extract, match, and split strings using regular expressions, a powerful way to express patterns.
