For this week, the topic we discussed is character strings in R. This lab’s content is a steppingstone for text  analysis.  We started with introducing the concept of characters, character strings, and character string vectors in R. Then, we talked about operations on strings such as getting substring and combining different character strings.  Finally, we learned about extracting and replacing certain patterns within a text-form data set.
