Anda dapat menggunakan fungsi na.omit()<\/strong> di R untuk menghapus semua kasus yang tidak lengkap dalam vektor, matriks, atau bingkai data.<\/span><\/p>\n

Fungsi ini menggunakan sintaks dasar berikut:<\/span><\/p>\n

 #omit NA values from vector<\/span>\nx <- na. omitted<\/span> (x)\n\n#omit rows with NA in any column of data frame\n<\/span>df <- na. omitted<\/span> (df)\n\n#omit rows with NA in specific column of data frame\n<\/span>df <- df[ !<\/span> (is. na<\/span> (df$column)), ]\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan fungsi ini dalam praktiknya.<\/span><\/p>\n
 Contoh 1: Hilangkan nilai NA dari vektor<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghilangkan semua nilai NA dari sebuah vektor:<\/span><\/p>\n
 #definevector\nx <- c(1, 24, NA, 6, NA, 9)<\/span>\n\n#omit NA values from vector<\/span>\nx <- na. omitted<\/span> (x)\n\nx\n\n[1] 1 24 6 9\nattr(,\"na.action\")\n[1] 3 5\nattr(,\"class\")\n[1] \u201comitted\u201d\n<\/strong><\/pre>\n
 Baris pertama keluaran menampilkan vektor tanpa nilai NA sedangkan dua baris berikutnya menampilkan informasi tambahan tentang lokasi nilai NA.<\/span><\/p>\n
 Kita dapat menggunakan kode berikut untuk mengembalikan vektor tanpa nilai NA:<\/span><\/p>\n
 #definevector\nx <- c(1, 24, NA, 6, NA, 9)<\/span>\n\n#omit NA values from vector<\/span>\nx <- as. numeric<\/span> (na. omit<\/span> (x))\n\nx\n\n[1] 1 24 6 9\n<\/strong><\/pre>\n
 Contoh 2: Hilangkan baris dengan NA di kolom mana pun pada bingkai data<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara menghilangkan semua baris dengan nilai NA di kolom mana pun dalam bingkai data:<\/span><\/p>\n
 #define data frame\ndf <- data. frame<\/span> (x=c(1, 24, NA, 6, NA, 9),\n                 y=c(NA, 3, 4, 8, NA, 12),\n                 z=c(NA, 7, 5, 15, 7, 14))\n\n#view data frame\n<\/span>df\n\n   X Y Z\n1 1 NA NA\n2 24 3 7\n3 NA 4 5\n4 6 8 15\n5 NA NA 7\n6 9 12 14<\/span>\n\n#omit rows with NA value in any column data frame<\/span>\ndf <- na. omitted<\/span> (df)\n\n#view data frame<\/span> \ndf\n\n   X Y Z\n2 24 3 7\n4 6 8 15\n6 9 12 14\n<\/strong><\/pre>\n
 Contoh 3: Hilangkan baris dengan NA di kolom tertentu pada bingkai data<\/strong><\/span><\/h3>\n
 Untuk menghilangkan baris dengan nilai NA pada kolom tertentu pada frame data, sebenarnya lebih mudah menggunakan fungsi is.na()<\/strong> sebagai berikut:<\/span><\/p>\n
 #define data frame\ndf <- data. frame<\/span> (x=c(1, 24, NA, 6, NA, 9),\n                 y=c(NA, 3, 4, 8, NA, 12),\n                 z=c(NA, 7, 5, 15, 7, 14))\n\n#view data frame\n<\/span>df\n\n   X Y Z\n1 1 NA NA\n2 24 3 7\n3 NA 4 5\n4 6 8 15\n5 NA NA 7\n6 9 12 14<\/span>\n\n<\/span>#remove rows with NA value in x<\/em> column<\/span>\ndf <- df[ !<\/span> (is. na<\/span> (df$x)), ]\n\n#view data frame<\/span> \ndf\n\n   X Y Z\n1 1 NA NA\n2 24 3 7\n4 6 8 15\n6 9 12 14<\/strong><\/pre>\n
