\n

Anda dapat menggunakan sintaks dasar berikut untuk memilih kolom berdasarkan indeks di R:<\/span><\/p>\n

 #select specific columns by index\n<\/span>df[, c(1, 4)]\n\n#select specific columns in index range\n<\/span>df[, 1:3]\n\n#exclude specific columns by index\n<\/span>df[, -c(2, 5)]\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan sintaksis ini dalam praktiknya dengan bingkai data berikut:<\/span><\/p>\n
 #create data frame<\/span>\ndf <- data. frame<\/span> (team=c('A', 'B', 'C', 'D', 'E'),\n                 points=c(99, 90, 86, 88, 95),\n                 assists=c(33, 28, 31, 39, 34),\n                 rebounds=c(30, 28, 24, 24, 28),\n                 blocks=c(7, 7, 5, 9, 13))\n\n#view data frame<\/span>\ndf\n\n  team points assists rebounds blocks\n1 A 99 33 30 7\n2 B 90 28 28 7\n3 C 86 31 24 5\n4 D 88 39 24 9\n5 E 95 34 28 13\n<\/strong><\/pre>\n
 Contoh 1: pilih kolom berdasarkan indeks<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara memilih kolom tertentu berdasarkan indeks:<\/span><\/p>\n
 #select columns in 1st and 4th position<\/span>\ndf[, c(1, 4)]\n\n  team rebounds\n1 to 30\n2 B 28\n3 C 24\n4 D 24\n5 E 28\n<\/strong><\/pre>\n
 Contoh 2: Pilih Kolom dari Rentang Indeks<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara memilih kolom tertentu dalam rentang indeks:<\/span><\/p>\n
 #select columns in positions 1 through 3<\/span>\ndf[, 1:3]\n\n  team points assists\n1 A 99 33\n2 B 90 28\n3 C 86 31\n4 D 88 39\n5 E 95 34<\/span><\/span><\/strong><\/pre>\n
 Contoh 3: kecualikan kolom berdasarkan indeks<\/strong><\/h3>\n
 Kode berikut menunjukkan cara mengecualikan kolom tertentu berdasarkan indeks:<\/span><\/p>\n
 #select all columns except columns in positions 2 and 5\ndf[, -c(2, 5)]\n\n  team assists rebounds\n1 to 33 30\n2 B 28 28\n3 C 31 24\n4 D 39 24\n5 E 34 28\n<\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa ini mengembalikan semua kolom dalam bingkai data kecuali kolom pada posisi indeks 2 dan 5.<\/span><\/span><\/p>\n
