Seringkali Anda mungkin ingin menghitung rata-rata grup dalam R. Anda dapat menggunakan tiga metode untuk melakukannya:<\/span><\/p>\n

Metode 1: Gunakan basis R.<\/strong><\/span><\/p>\n

 aggregate(df$col_to_aggregate, list(df$col_to_group_by), FUN= mean<\/span> )<\/span><\/strong><\/pre>\n
 Metode 2: Gunakan paket dplyr().<\/strong><\/span><\/p>\n
 library<\/span> (dplyr)\n\ndf %>%\n  group_by<\/span> (col_to_group_by) %>%\n  summarise_at<\/span> (vars(col_to_aggregate), list(name = mean<\/span> ))\n<\/b><\/span><\/pre>\n
 Metode 3: Gunakan paket data.table.<\/strong><\/span><\/p>\n
 library<\/span> (data.table)\n\ndt[ ,list(mean= mean<\/span> (col_to_aggregate)), by=col_to_group_by]\n<\/b><\/span><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan masing-masing metode ini dalam praktik.<\/span><\/p>\n
 Metode 1: Hitung rata-rata per kelompok menggunakan basis R<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menggunakan fungsi R database Aggregate()<\/strong> untuk menghitung poin rata-rata yang dicetak per tim dalam bingkai data berikut:<\/span><\/p>\n
 #create data frame<\/span>\ndf <- data.frame(team=c('a', 'a', 'b', 'b', 'b', 'c', 'c'),\n                 pts=c(5, 8, 14, 18, 5, 7, 7),\n                 rebs=c(8, 8, 9, 3, 8, 7, 4))\n\n<\/span>#view data frame<\/span>\ndf\n\n  team pts rebs\n1 to 5 8\n2 to 8 8\n3 b 14 9\n4 b 18 3\n5 b 5 8\n6 c 7 7\n7 c 7 4\n\n<\/span>#find mean points scored by team\n<\/span><\/span>aggregate(df$pts, list(df$team), FUN= mean<\/span> )\n\n  Group.1 x\n1 to 6.50000\n2 b 12.33333\n3 to 7.00000\n<\/span><\/strong><\/pre>\n
 Metode 2: Hitung rata-rata per kelompok menggunakan dplyr<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menggunakan fungsi group_by<\/strong> ()<\/strong> dan summarise_at()<\/strong> dari paket dplyr<\/strong> untuk menghitung rata-rata poin yang dicetak per tim dalam bingkai data berikut:<\/span><\/p>\n
 library<\/span> (dplyr)<\/span><\/b>\n\n#create data frame<\/span>\ndf <- data.frame(team=c('a', 'a', 'b', 'b', 'b', 'c', 'c'),\n                 pts=c(5, 8, 14, 18, 5, 7, 7),\n                 rebs=c(8, 8, 9, 3, 8, 7, 4))\n\n#find mean points scored by team<\/span>\ndf %>%\ngroup_by<\/span> (team) %>%\nsummarise_at<\/span> (vars(pts), list(name = mean<\/span> ))\n\n# A tibble: 3 x 2\n  team name\n  <fct> <dbl>\n1 to 6.5\n2 b 12.3\n3 v 7<\/b>\n<\/span><\/strong><\/pre>\n
 Metode 3: Hitung rata-rata berdasarkan kelompok menggunakan data.tabel<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghitung rata-rata poin yang dicetak per tim dalam bingkai data berikut:<\/span><\/p>\n
 library<\/span> (data.table)<\/span><\/b>\n\n#create data frame<\/span>\ndf <- data.frame(team=c('a', 'a', 'b', 'b', 'b', 'c', 'c'),\n                 pts=c(5, 8, 14, 18, 5, 7, 7),\n                 rebs=c(8, 8, 9, 3, 8, 7, 4))\n\n#convert data frame to data table<\/span> \nsetDT(df)\n\n#find mean points scored by team<\/span>\ndf[,list(mean= mean<\/span> (pts)), by=team]\n\n   team mean\n1: to 6.50000\n2:b12.33333\n3: c 7.00000<\/b><\/span><\/strong><\/pre>\n
 Perhatikan bahwa ketiga metode memberikan hasil yang sama.<\/span><\/p>\n
