Anda dapat menggunakan metode berikut untuk menemukan nilai unik dan kemudian mengurutkannya di R:<\/span><\/p>\n

Metode 1: Temukan Nilai Unik dalam Vektor dan Urutkan<\/strong><\/span><\/p>\n

 #get unique values sorted in ascending order\n<\/span>sort(unique(data))\n<\/strong><\/pre>\n
 Metode 2: Temukan baris unik dalam bingkai data dan urutkan<\/strong><\/span><\/p>\n
 #remove duplicate rows in data frame\n<\/span>df_new = df[!duplicated(df), ]\n\n#display unique rows sorted by values in specific column\n<\/span>df_new = df_new[order(df_new$my_column), ]\n<\/span><\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan masing-masing metode dalam praktik.<\/span><\/p>\n
 Contoh 1: Temukan Nilai Unik dalam Vektor dan Urutkan<\/strong><\/span><\/h2>\n
 Misalkan kita memiliki vektor berikut di R:<\/span><\/p>\n
 #create vector of values\n<\/span>data <- c(2, 2, 4, 7, 2, 4, 14, 7, 10, 7)\n<\/span><\/strong><\/pre>\n
 Kita dapat menggunakan sintaks berikut untuk menemukan nilai unik dalam vektor dan mengurutkannya:<\/span><\/p>\n
 #get unique values sorted in ascending order\n<\/span>sort(unique(data))\n\n[1] 2 4 7 10 14\n<\/span><\/strong><\/pre>\n
 Perhatikan bahwa nilai unik vektor dikembalikan dalam urutan menaik.<\/span><\/p>\n
 Kita juga dapat menggunakan argumen descending=TRUE<\/strong> untuk mengurutkan nilai unik dalam urutan menurun:<\/span><\/p>\n
 #get unique values sorted in descending order\n<\/span>sort(unique(data), decreasing= TRUE<\/span> )\n\n[1] 14 10 7 4 2<\/span><\/strong><\/pre>\n
 Perhatikan bahwa nilai unik vektor dikembalikan dalam urutan menurun.<\/span><\/p>\n
 Contoh 2: Temukan nilai unik dalam bingkai data dan urutkan<\/strong><\/span><\/h2>\n
 Misalkan kita memiliki bingkai data berikut di R:<\/span><\/p>\n
 #create data frame\n<\/span>df <- data. frame<\/span> (team=c('A', 'B', 'A', 'A', 'A', 'B', 'B', 'B', 'A', 'B'),\n                 points=c(2, 10, 7, 7, 2, 4, 14, 7, 2, 7))\n\n#view data frame\n<\/span>df\n\n   team points\n1 TO 2\n2 B 10\n3 to 7\n4 to 7\n5 to 2\n6 B 4\n7 B 14\n8 B 7\n9 to 2\n10 B 7<\/span><\/strong><\/pre>\n
 Kita dapat menggunakan sintaks berikut untuk menemukan baris unik dalam bingkai data dan mengurutkannya berdasarkan nilai kolom tim<\/strong> :<\/span><\/p>\n
 #remove duplicate rows in data frame\n<\/span>df_new = df[ !<\/span> duplicated(df), ]\n\n#sort unique rows based on values in team column\n<\/span>df_new = df_new[order(df_new$team, df_new$points), ]\n\n#view new data frame\n<\/span>df_new\n\n  team points\n1 TO 2\n3 to 7\n2 B 4\n6 B 7\n7 B 10\n8 B 14<\/span><\/strong><\/pre>\n
 Perhatikan bahwa baris unik dikembalikan dan diurutkan berdasarkan nilai di kolom Tim<\/strong> dan kemudian nilai di kolom Poin<\/strong> .<\/span><\/p>\n
