Thank you for thisbthis is wxactly what i need. Suppose you want to arrange by two columns, would you add that column in the same arrange function but after a comma?

Hi, thanks for sharing knowledge! I am grouping df by class and then summarising the Freq variable by using sum function. I am using exact same code you demonstrated; however, my output is not grouped by class, I only get the sum of entire Freq column printed, not grouped by class as you demonstrated. Am I missing something?

_titanic_df %>% group_by(Class) %>% summarise(num_passg_class = sum(Freq))_

*the output is*
num_passg_class
1 2201


for the code _summarise(titanic_df, num_passg_class = sum(Freq))_
*the output is*
num_passg_class
1 2201
