Seringkali Anda mungkin ingin mencari nilai maksimum setiap grup dalam bingkai data di R. Untungnya, hal ini mudah dilakukan menggunakan fungsi dalam paket dplyr<\/a> .<\/span><\/p>\n

Tutorial ini menjelaskan cara melakukan ini menggunakan bingkai data berikut:<\/span><\/p>\n

 #create data frame<\/span>\ndf <- data.frame(team = c('A', 'A', 'A', 'B', 'B', 'B', 'B'),\n                 position = c('G', 'F', 'F', 'G', 'G', 'G', 'F'),\n                 points = c(12, 15, 19, 22, 34, 34, 39))\n\n#view data frame\n<\/span>df\n\n  team position points\n1 AG 12\n2 AF15\n3 FY 19\n4 BG 22\n5 BG 34\n6 BG 34\n7 BF 39\n<\/strong><\/pre>\n
 Contoh 1: Temukan nilai maksimum per grup<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara mencari nilai maksimum per tim per posisi:<\/span><\/p>\n
 library(dplyr)<\/span>\n\n#find max value by team and position<\/span>\ndf %>%\n  group_by<\/span> (team, position) %>%\n  summarize<\/span> (max = max(points, na.rm= TRUE<\/span> ))\n\n# A tibble: 4 x 3\n# Groups: team [?]\n  team position max\n      \n1AF 19.0\n2 AG 12.0\n3 BF 39.0\n4 BG 34.0<\/strong><\/pre>\n
 Contoh 2: Mengembalikan baris yang berisi nilai maksimum per grup<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara mengembalikan baris yang berisi nilai maksimum per tim dan per posisi:<\/span><\/p>\n
 library(dplyr)<\/span>\n\n#find rows that contain max points by team and position<\/span>\ndf %>%\n  group_by<\/span> (team, position) %>%\n  filter<\/span> (points == max(points, na.rm= TRUE<\/span> ))\n\n# A tibble: 5 x 3\n# Groups: team, position [4]\n  team position points\n       \n1 AG 12.0\n2AF 19.0\n3 BG 34.0\n4 BG 34.0\n5BF 39.0<\/strong><\/pre>\n
 Contoh 3: Mengembalikan satu baris yang berisi nilai maksimum per grup<\/strong><\/span><\/h3>\n
 Pada contoh sebelumnya, ada dua pemain yang memiliki jumlah poin maksimal di tim A dan keduanya berada di posisi G. Jika Anda hanya ingin mengembalikan pemain pertama dengan nilai maksimal ke grup, Anda bisa menggunakan irisan( ) fungsi.<\/strong> beroperasi sebagai berikut:<\/span><\/p>\n
 library(dplyr)<\/span>\n\n#find rows that contain max points by team and position<\/span>\ndf %>%\n  group_by<\/span> (team, position) %>%\n  slice<\/span> (which.max(points))\n\n# A tibble: 4 x 3\n# Groups: team, position [4]\n  team position points\n       \n1AF 19.0\n2 AG 12.0\n3 BF 39.0\n4 BG 34.0<\/strong><\/pre>\n
