Ada tiga cara umum untuk menghapus kolom dari bingkai data di R berdasarkan nama:<\/span><\/p>\n

Metode 1: Gunakan Basis R<\/strong><\/span><\/p>\n

 #drop col2 and col4 from data frame<\/span>\ndf_new <- subset(df, select = -c(col2, col4))\n<\/strong><\/pre>\n
 Metode 2: gunakan dplyr<\/strong><\/span><\/p>\n
 library<\/span> (dplyr)\n\n#drop col2 and col4 from data frame<\/span>\ndf_new <- df %>% select(-c(col2, col4))\n<\/strong><\/pre>\n
 Metode 3: Gunakan data.tabel<\/strong><\/span><\/p>\n
 library<\/span> (data.table)\n\n#convert data frame to data table<\/span>\ndt <- setDT(df)\n\n#drop col2 and col4 from data frame<\/span>\ndt[, c(' col2<\/span> ', ' col4<\/span> '):=NULL]\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan setiap metode dalam praktik dengan kerangka data berikut di R:<\/span><\/p>\n
 #create data frame\n<\/span>df <- data. frame<\/span> (team=c('A', 'A', 'B', 'B', 'C', 'C', 'C', 'D'),\n                 points=c(12, 15, 22, 29, 35, 24, 11, 24),\n                 rebounds=c(10, 4, 4, 15, 14, 9, 12, 8),\n                 assists=c(7, 7, 5, 8, 19, 14, 11, 10))\n\n#view data frame\n<\/span>df\n\n  team points rebound assists\n1 A 12 10 7\n2 to 15 4 7\n3 B 22 4 5\n4 B 29 15 8\n5 C 35 14 19\n6 C 24 9 14\n7 C 11 12 11\n8 D 24 8 10\n<\/span><\/span><\/strong><\/pre>\n
 Contoh 1: Hapus Kolom berdasarkan Nama Menggunakan Basis R<\/strong><\/span><\/h2>\n
 Kode berikut menunjukkan cara menghapus kolom titik<\/strong> dan kolom pembantu<\/strong> dari bingkai data menggunakan fungsi subset()<\/strong> di basis R:<\/span><\/p>\n
 #create new data frame by dropping points and assists columns\n<\/span>df_new <- subset(df, select = -c(points, assists))\n\n#view new data frame\n<\/span>df_new\n\n  team rebounds\n1 to 10\n2 to 4\n3 B 4\n4 B 15\n5 C 14\n6 C 9\n7 C 12\n8 D 8\n<\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa kolom poin<\/strong> dan bantuan<\/strong> telah dihapus dari bingkai data baru.<\/span><\/span><\/p>\n
 Contoh 2: Hapus kolom berdasarkan nama menggunakan dplyr<\/strong><\/span><\/h2>\n
 Kode berikut menunjukkan cara menghapus kolom titik<\/strong> dan kolom pembantu<\/strong> dari bingkai data menggunakan fungsi select()<\/strong> dari paket dplyr:<\/span><\/p>\n
 library<\/span> (dplyr)\n\n#create new data frame by dropping points and assists columns\n<\/span>df_new <- df %>% select(-c(points, assists))\n\n#view new data frame\n<\/span>df_new\n\n  team rebounds\n1 to 10\n2 to 4\n3 B 4\n4 B 15\n5 C 14\n6 C 9\n7 C 12\n8 D 8<\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa kolom poin<\/strong> dan bantuan<\/strong> telah dihapus dari bingkai data baru.<\/span><\/p>\n
 Contoh 3: Hapus kolom berdasarkan nama menggunakan data.table<\/strong><\/span><\/h2>\n
 Kode berikut menunjukkan cara menghapus kolom titik<\/strong> dan kolom pembantu<\/strong> dari bingkai data dengan mengatur kedua kolom ke NULL menggunakan paket data.table:<\/span><\/p>\n
 library<\/span> (data.table)\n\n#convert data frame to data table<\/span>\ndt <- setDT(df)\n\n#drop points and assists columns\n<\/span>dt[, c(' points<\/span> ', ' assists<\/span> '):=NULL]\n\n#view updated data table\n<\/span>dt\n\n   team rebounds\n1: At 10\n2: A 4\n3:B4\n4:B15\n5:C14\n6: C 9\n7:C12\n8: D 8\n<\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa kolom poin<\/strong> dan bantuan<\/strong> telah dihapus dari tabel data baru.<\/span><\/p>\n
 Catatan<\/strong> : Ketiga metode memberikan hasil yang sama, namun metode dplyr<\/strong> dan data.table<\/strong> akan cenderung lebih cepat ketika bekerja dengan kumpulan data yang sangat besar.<\/span><\/p>\n
