General Data Wrangling and Analysis Resources

Because most material that discusses data wrangling and analysis with the dplyr packges does so in a way that covers all of the verbs discussed in this course, I have chosen not to separate them by lesson. Instead, here are some helpful resources for learning more about all of the tidyverse verbs discussed in this course:

  1. Hello, I have a question. how could I get the subtotals by group on the same DF that we obtain when we use de group by + summarise?

    We get something like this, but i would like to see on the same table the sub totals (by gender) and the grand total (which should by 10.000)
