Anda dapat menggunakan fungsi row.names()<\/strong> untuk mendapatkan dan menyetel nama baris bingkai data dengan cepat di R.<\/span><\/p>\n

Tutorial ini memberikan beberapa contoh penggunaan praktis fungsi ini pada dataset mtcars<\/strong> yang dibangun di R:<\/span><\/p>\n

 #view first six rows of mtcars<\/em><\/span>\nhead(mtcars)\n\n                   mpg cyl disp hp drat wt qsec vs am gear carb\nMazda RX4 21.0 6 160 110 3.90 2.620 16.46 0 1 4 4\nMazda RX4 Wag 21.0 6 160 110 3.90 2.875 17.02 0 1 4 4\nDatsun 710 22.8 4 108 93 3.85 2.320 18.61 1 1 4 1\nHornet 4 Drive 21.4 6 258 110 3.08 3.215 19.44 1 0 3 1\nHornet Sportabout 18.7 8 360 175 3.15 3.440 17.02 0 0 3 2\nValiant 18.1 6 225 105 2.76 3,460 20.22 1 0 3 1<\/strong><\/pre>\n
 Cara mendapatkan nama baris<\/strong><\/span><\/h3>\n
 Anda dapat menggunakan sintaks berikut untuk menampilkan nama baris pertama bingkai data mtcars<\/em> :<\/span><\/p>\n
 #view first six row names of mtcars<\/em><\/span>\nhead( row<\/span> . names<\/span> (mtcars))\n\n[1] \"Mazda RX4\" \"Mazda RX4 Wag\" \"Datsun 710\"       \n[4] \"Hornet 4 Drive\" \"Hornet Sportabout\" \"Valiant\" \n<\/strong><\/pre>\n
 Cara mengubah nama baris<\/strong><\/span><\/h3>\n
 Anda dapat menggunakan sintaks berikut untuk mengubah nama baris tertentu:<\/span><\/p>\n
 #change the row name called Datsun710<\/em> to 710<\/em>\n<\/span>row<\/span> . names<\/span> (mtcars)[ row<\/span> . names<\/span> (mtcars) == \" Datsun 710<\/span> \"] <- \" 710<\/span> \"\n\n#view first six row names of mtcars<\/em><\/span> \nhead(mtcars)\n\n                   mpg cyl disp hp drat wt qsec vs am gear carb\nMazda RX4 21.0 6 160 110 3.90 2.620 16.46 0 1 4 4\nMazda RX4 Wag 21.0 6 160 110 3.90 2.875 17.02 0 1 4 4\n710 22.8 4 108 93 3.85 2.320 18.61 1 1 4 1\nHornet 4 Drive 21.4 6 258 110 3.08 3.215 19.44 1 0 3 1\nHornet Sportabout 18.7 8 360 175 3.15 3.440 17.02 0 0 3 2\nValiant 18.1 6 225 105 2.76 3,460 20.22 1 0 3 1\n<\/strong><\/pre>\n
 Bagaimana cara mengubah semua nama baris<\/strong><\/span><\/h3>\n
 Anda dapat menggunakan sintaks berikut untuk mengganti semua nama baris dengan daftar bilangan bulat yang dimulai dari 1:<\/span><\/p>\n
 #change row names to a list of integers\n<\/span>row.names (mtcars) <- 1: nrow<\/span> (mtcars)\n\n#view first six row names of mtcars<\/em><\/span> \nhead(mtcars)\n\n   mpg cyl disp hp drat wt qsec vs am gear carb\n1 21.0 6 160 110 3.90 2.620 16.46 0 1 4 4\n2 21.0 6 160 110 3.90 2.875 17.02 0 1 4 4\n3 22.8 4 108 93 3.85 2.320 18.61 1 1 4 1\n4 21.4 6 258 110 3.08 3.215 19.44 1 0 3 1\n5 18.7 8 360 175 3.15 3.440 17.02 0 0 3 2\n6 18.1 6 225 105 2.76 3,460 20.22 1 0 3 1\n<\/span><\/span><\/strong><\/pre>\n
 Anda juga dapat menggunakan fungsi paste()<\/strong> untuk menambahkan kata di depan setiap nama baris:<\/span><\/p>\n
 #change row names\n<\/span>row.names (mtcars) <- paste(\" row<\/span> \", 1: nrow<\/span> (mtcars))\n\n#view first six row names of mtcars<\/em><\/span> \nhead(mtcars)\n\n       mpg cyl disp hp drat wt qsec vs am gear carb\nrow 1 21.0 6 160 110 3.90 2.620 16.46 0 1 4 4\nrow 2 21.0 6 160 110 3.90 2.875 17.02 0 1 4 4\nrow 3 22.8 4 108 93 3.85 2.320 18.61 1 1 4 1\nrow 4 21.4 6 258 110 3.08 3.215 19.44 1 0 3 1\nrow 5 18.7 8 360 175 3.15 3.440 17.02 0 0 3 2\nrow 6 18.1 6 225 105 2.76 3.460 20.22 1 0 3 1\n<\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa setiap baris sekarang memiliki kata “baris” yang ditambahkan di awal.<\/span><\/p>\n
