Terkadang Anda mungkin tertarik untuk mengkode ulang nilai tertentu ke dalam bingkai data di R. Untungnya, hal ini dapat dengan mudah dilakukan menggunakan fungsi recode()<\/a> dari paket dplyr.<\/span><\/p>\n

Tutorial ini menunjukkan beberapa contoh penggunaan praktis fungsi ini.<\/span><\/p>\n

Contoh 1: Kode ulang satu kolom dalam kerangka data<\/strong><\/span><\/h3>\n

Kode berikut menunjukkan cara mengkode ulang satu kolom dalam kerangka data:<\/span><\/p>\n

 library(dplyr)<\/span>\n<\/span>\n#create dataframe<\/span> \ndf <- data.frame(player = c('A', 'B', 'C', 'D'),\n                 points = c(24, 29, 13, 15),\n                 result = c('Win', 'Loss', 'Win', 'Loss'))\n\n#view dataframe<\/span> \ndf\n\n#change 'Win' and 'Loss' to '1' and '0'<\/span>\ndf %>% mutate<\/span> (result=recode(result, ' Win<\/span> '='1', ' Loss<\/span> '='0'))\n\n       player points result\n1 to 24 1\n2 B 29 0\n3 C 13 1\n4 D 15 0\n<\/strong><\/pre>\n
 Contoh 2: Kode ulang satu kolom dalam bingkai data dan berikan nilai NA<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara mengode ulang satu kolom dalam bingkai data dan menetapkan nilai NA<\/strong> ke nilai apa pun yang tidak secara eksplisit diberi nilai baru:<\/span><\/p>\n
 library(dplyr)\n<\/span>\n#create dataframe<\/span> \ndf <- data.frame(player = c('A', 'B', 'C', 'D'),\n                 points = c(24, 29, 13, 15),\n                 result = c('Win', 'Loss', 'Win', 'Loss'))\n\n#view dataframe<\/span> \ndf\n\n#change 'Win' to '1' and give all other values a value of NA<\/span>\ndf %>% mutate<\/span> (result=recode(result, ' Win<\/span> '='1', .default<\/span> =NA_character_))\n\n       player points result\n1 to 24 1\n2 B 29 <NA>\n3 C 13 1\n4 D 15 <NA><\/strong><\/pre>\n
 Contoh 3: kode ulang beberapa kolom dalam kerangka data<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara mengkode ulang beberapa kolom sekaligus dalam kerangka data:<\/span><\/p>\n
 library(dplyr)\n<\/span>\n#create dataframe<\/span> \ndf <- data.frame(player = c('A', 'B', 'C', 'D'),\n                 points = c(24, 29, 13, 15),\n                 result = c('Win', 'Loss', 'Win', 'Loss'))\n\n#recode 'player' and 'result' columns<\/span>\ndf %>% mutate<\/span> (player=recode(player, ' A<\/span> '='Z'),\n              result=recode(result, ' Win<\/span> '='1', ' Loss<\/span> '='0'))\n\n       player points result\n1 Z 24 1\n2 B 29 0\n3 C 13 1\n4 D 15 0<\/strong><\/pre>\n
