Anda dapat menggunakan sintaks berikut untuk memilih kolom tertentu dalam bingkai data berbasis R:<\/span><\/p>\n

 #select columns by name\n<\/span>df[c(' col1<\/span> ', ' col2<\/span> ', ' col4<\/span> ')]\n\n#select columns by index\n<\/span>df[c(1, 2, 4)]\n<\/strong><\/pre>\n
 Alternatifnya, Anda dapat menggunakan fungsi select()<\/strong> dari paket dplyr<\/a> :<\/span><\/p>\n
 library<\/span> (dplyr)<\/span>\n\n#select columns by name\n<\/span>df %>%\n  select(col1, col2, col4)\n\n#select columns by index\n<\/span>df %>%\n  select(1, 2, 4)\n<\/strong><\/pre>\n
 Untuk kumpulan data yang sangat besar, disarankan untuk menggunakan metode dplyr karena fungsi select()<\/strong> cenderung lebih cepat daripada fungsi dasar R.<\/span><\/p>\n
 Contoh berikut menunjukkan cara menggunakan kedua metode ini dalam praktik dengan kerangka data berikut:<\/span><\/p>\n
 #create data frame<\/span>\ndf <- data. frame<\/span> (a=c(1, 3, 4, 6, 8, 9),\n                 b=c(7, 8, 8, 7, 13, 16),\n                 c=c(11, 13, 13, 18, 19, 22),\n                 d=c(12, 16, 18, 22, 29, 38))\n\n#view data frame\n<\/span>df\n\n  abcd\n1 1 7 11 12\n2 3 8 13 16\n3 4 8 13 18\n4 6 7 18 22\n5 8 13 19 29\n6 9 16 22 38\n<\/strong><\/pre>\n
 Contoh 1: Pilih kolom tertentu menggunakan Basis R (berdasarkan nama)<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara memilih kolom tertentu berdasarkan nama menggunakan basis R:<\/span><\/p>\n
 #select columns by name\n<\/span>df[c(' a<\/span> ', ' b<\/span> ', ' d<\/span> ')]\n\n  abd\n1 1 7 12\n2 3 8 16\n3 4 8 18\n4 6 7 22\n5 8 13 29\n6 9 16 38\n<\/strong><\/pre>\n
 Contoh 2: Pilih kolom tertentu menggunakan basis R (berdasarkan indeks)<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara memilih kolom tertentu berdasarkan indeks menggunakan basis R:<\/span><\/p>\n
 #select columns by index\n<\/span>df[c(1, 2, 4)]\n\n  abd\n1 1 7 12\n2 3 8 16\n3 4 8 18\n4 6 7 22\n5 8 13 29\n6 9 16 38<\/strong><\/pre>\n
 Contoh 3: Pilih kolom tertentu menggunakan dplyr (berdasarkan nama)<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara memilih kolom tertentu berdasarkan nama menggunakan dplyr:<\/span><\/p>\n
 library<\/span> (dplyr)<\/span>\n\n#select columns by name\n<\/span>df %>%\n  select(a, b, d)\n\n  abd\n1 1 7 12\n2 3 8 16\n3 4 8 18\n4 6 7 22\n5 8 13 29\n6 9 16 38<\/strong><\/pre>\n
 Contoh 4: Pilih kolom tertentu menggunakan dplyr (berdasarkan indeks)<\/strong><\/span><\/h3>\n
 Kode berikut menunjukkan cara memilih kolom tertentu berdasarkan indeks menggunakan dplyr:<\/span><\/p>\n
 library<\/span> (dplyr)<\/span>\n\n#select columns by index\n<\/span>df %>%\n  select(1, 2, 4)\n\n  abd\n1 1 7 12\n2 3 8 16\n3 4 8 18\n4 6 7 22\n5 8 13 29\n6 9 16 38<\/strong><\/pre>\n
