使用艺术家、歌曲和持续时间变量制作数据框

Question

I'm new with tidyverse in R.

I have a dataframe radio , from a radio channel, from a specfic date with variables: artist, song, duration.

My aim is to find which artist that has the most different songs playing on the choosen date.

 radio %>% select(artist, song) %>% arrange...

and then I'm lost. Please help if anyone is good at this.

Answer 1

you can group_by artist song and then compute the different songs:

radio %>% 
  select(artist, song) %>%
  group_by(artist) %>%
  summarise(n_song = n_distinct(song), .groups = "drop") %>%
  arrange(-n_song)
