Anda dapat menggunakan metode berikut untuk hanya menyimpan kolom tertentu dalam bingkai data di R:<\/span><\/p>\n

Metode 1: Tentukan kolom mana yang akan disimpan<\/strong><\/span><\/p>\n

 #only keep columns 'col1' and 'col2'<\/span>\nnew_df = subset(df, select = c(col1, col2))\n<\/strong><\/pre>\n
 Metode 2: Tentukan kolom yang akan dihapus<\/strong><\/span><\/p>\n
 #drop columns 'col3' and 'col4'<\/span>\nnew_df = subset(df, select = c(col3, col4))\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan setiap metode dengan bingkai data berikut di R:<\/span><\/p>\n
 #create data frame\n<\/span>df <- data. frame<\/span> (team=c('A', 'A', 'A', 'B', 'B', 'B'),\n                 points=c(19, 14, 14, 29, 25, 30),\n                 assists=c(4, 5, 5, 4, 12, 10),\n                 rebounds=c(9, 7, 7, 6, 10, 11))\n\n#view data frame\n<\/span>df\n\n  team points assists rebounds\n1 A 19 4 9\n2 A 14 5 7\n3 to 14 5 7\n4 B 29 4 6\n5 B 25 12 10\n6 B 30 10 11<\/strong><\/pre>\n
 Metode 1: Tentukan kolom mana yang akan disimpan<\/strong><\/span><\/h2>\n
 Kode berikut menunjukkan cara menentukan bingkai data baru yang hanya mempertahankan kolom “tim” dan “kehadiran”:<\/span><\/p>\n
 #keep 'team' and 'assists' columns\n<\/span>new_df = subset(df, select = c(team, assists))\n\n#view new data frame\n<\/span>new_df\n\n  team assists\n1 to 4\n2 to 5\n3 to 5\n4 B 4\n5 B 12\n6 B 10\n<\/span><\/span><\/strong><\/pre>\n
 Bingkai data yang dihasilkan hanya mempertahankan dua kolom yang kami tentukan.<\/span><\/p>\n
 Metode 2: Tentukan kolom yang akan dihapus<\/strong><\/span><\/h2>\n
 Kode berikut menunjukkan cara menentukan bingkai data baru yang menghilangkan kolom “tim” dan “kehadiran” dari bingkai data asli:<\/span><\/p>\n
 #drop 'team' and 'assists' columns\n<\/span>new_df = subset(df, select = -c(team, assists))\n\n#view new data frame\n<\/span>new_df\n\n  rebound points\n1 19 9\n2 14 7\n3 14 7\n4 29 6\n5 25 10\n6 30 11\n<\/span><\/span><\/strong><\/pre>\n
 Bingkai data yang dihasilkan menghapus kolom “tim” dan “bantuan” dari bingkai data asli dan mempertahankan kolom yang tersisa.<\/span><\/p>\n
