Seringkali Anda mungkin ingin menghapus baris yang berisi beberapa atau semua NA (nilai yang hilang) dalam bingkai data di R.<\/span><\/p>\n

Tutorial ini menjelaskan cara menghapus baris ini menggunakan Basic R dan paket Tidyr<\/a> . Kami akan menggunakan kerangka data berikut untuk setiap contoh berikut:<\/span><\/p>\n

 #create data frame with some missing values<\/span>\ndf <- data.frame(points = c(12, NA, 19, 22, 32),\n                 assists = c(4, NA, 3, NA, 5),\n                 rebounds = c(5, NA, 7, 12, NA))\n\n#view data frame\n<\/span>df\n\n  points assists rebounds\n1 12 4 5\n2 NA NA NA\n3 19 3 7\n4 22 NA 12\n5 32 5 NA\n<\/strong><\/pre>\n
 Hapus NA menggunakan Base R<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menggunakan complete.cases()<\/strong> untuk menghapus semua baris dalam bingkai data yang memiliki nilai yang hilang di kolom<\/em> :<\/span><\/p>\n
 #remove all rows with a missing value in any<\/em> column<\/span>\ndf[ complete.cases<\/span> (df),]\n\n  points assists rebounds\n1 12 4 5\n3 19 3 7\n<\/strong><\/pre>\n
 Kode berikut menunjukkan cara menggunakan complete.cases()<\/strong> untuk menghapus semua baris dalam bingkai data yang memiliki nilai hilang di kolom tertentu<\/em> :<\/span><\/p>\n
 #remove all rows with a missing value in the third<\/em> column<\/span>\ndf[ complete.cases<\/span> (df[,3]),]\n\n  points assists rebounds\n1 12 4 5\n3 19 3 7\n4 22 NA 12\n\n#remove all rows with a missing value in either the first<\/em> or third<\/em> column\n<\/span>df[ complete.cases<\/span> (df[ , c(1,3)]),]\n\n  points assists rebounds\n1 12 4 5\n3 19 3 7\n4 22 NA 12\n<\/strong><\/pre>\n
 Hapus NA menggunakan Tidyr<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menggunakan drop_na()<\/strong> dari paket Tidyr untuk menghapus semua baris dalam bingkai data yang memiliki nilai yang hilang di kolom<\/em> :<\/span><\/p>\n
 #load tidyr package<\/span>\nlibrary(tidyr)<\/span>\n\n#remove all rows with a missing value in any<\/em> column<\/span>\ndf %>% drop_na()\n\n  points assists rebounds\n1 12 4 5\n3 19 3 7<\/strong><\/pre>\n
 Kode berikut menunjukkan cara menggunakan drop_na()<\/strong> dari paket Tidyr untuk menghapus semua baris dalam bingkai data yang memiliki nilai hilang di kolom tertentu<\/em> :<\/span><\/p>\n
 #load tidyr package<\/span>\nlibrary(tidyr)<\/span>\n\n#remove all rows with a missing value in the third<\/em> column<\/span>\ndf %>% drop_na(rebounds)\n\n  points assists rebounds\n1 12 4 5\n3 19 3 7\n4 22 NA 12<\/strong><\/pre>\n
