The data verb functions all take a data frame as their first argument and return a data frame as their output. The chaining syntax lets the output of one function become the input to the following function, so you do not have to repeat the name of the data frame.

Each of the following statements, EXCEPT one, will accomplish the same calculation. Identify the statement that does NOT match the others. O BabyNames %>% group_by( year, sex ) %>% summarise( totalBirths sum(count)) group_by( BabyNames, year, sex) %>% Bummarie
