Exercise

Import all tables

Next to the users, we're also interested in the tweats and comments tables. However, separate dbReadTable() calls for each and every one of the tables in your database would mean a lot of code duplication. Remember about the lapply() function? You can use it again here! A connection is already coded for you, as well as a vector table_names, containing the names of all the tables in the database.

Instructions

100 XP
  • Finish the lapply() function to import the users, tweats and comments tables in a single call. The result, a list of data frames, will be stored in the variable tables.
  • Print tables to check if you got it right.
