Exercises 6 - dplyr

We’ll continue to work on the same .Rmd file from the previous exercise.

6.1 Fix the BabyNameSupp Data

Edit your code chunk that reads the data in from a csv file and add the argument col_types = cols(sex = col_character()) to the read_csv() code.

6.2 Combining Data Sets with dplyr::bind_rows()

1. Write a quick note below your last R code chunk that mentions that we are going to combine the two data sets into one.

2. Use the bind_rows() function from dplyr to combine BabyNames & BabyNamesSupp via bind_rows(BabyNames, BabyNamesSupp) into an object called BabyNamesFull.

6.3 Filter and Arrange Rows

• Filter the BabyNamesFull data to include only the names we are interested in (Hint: use %in%). Just have this print out to the console.

• Continue the previous code to then reorder the rows descending on the count variable.
