Anda dapat menggunakan metode berikut untuk memilih baris acak dalam bingkai data di R menggunakan fungsi dalam paket dplyr<\/a> :<\/span><\/p>\n

Metode 1: Pilih sejumlah baris secara acak<\/strong><\/span><\/p>\n

 df %>% sample_n( 5<\/span> )\n<\/strong><\/pre>\n
 Fungsi ini secara acak memilih 5<\/strong> baris dari bingkai data.<\/span><\/p>\n
 Metode 2: pilih pecahan baris secara acak<\/strong><\/span><\/p>\n
 df %>% sample_frac( .25<\/span> )\n<\/strong><\/pre>\n
 Fungsi ini secara acak memilih 25%<\/strong> dari seluruh baris dalam bingkai data.<\/span><\/p>\n
 Contoh berikut menunjukkan cara menggunakan setiap metode dalam praktik dengan kerangka data berikut di R:<\/span><\/p>\n
 #create data frame\ndf <- data. frame<\/span> (team=c('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H'),\n                 points=c(10, 10, 8, 6, 15, 15, 12, 12),\n                 rebounds=c(8, 8, 4, 3, 10, 11, 7, 7))<\/span>\n\n#view data frame\ndf\n\n  team points rebounds\n1 to 10 8\n2 B 10 8\n3 C 8 4\n4 D 6 3\n5 E 15 10\n6 F 15 11\n7 G 12 7\n8:12 a.m. 7<\/span><\/span><\/strong><\/span><\/pre>\n
 Contoh 1: Pilih sejumlah baris secara acak<\/strong><\/span><\/h3>\n
 Kita dapat menggunakan kode berikut untuk memilih secara acak 5<\/strong> baris dari bingkai data:<\/span><\/p>\n
 library<\/span> (dplyr)\n\n#randomly select 5 rows from data frame<\/span>\ndf %>% sample_n( 5<\/span> )\n\n  team points rebounds\n1 F 15 11\n2 to 10 8\n3 D 6 3\n4 G 12 7\n5 B 10 8\n<\/strong><\/span><\/pre>\n
 Perhatikan bahwa lima baris dipilih secara acak dari bingkai data.<\/span><\/p>\n
 Contoh 2: pilih pecahan baris secara acak<\/strong><\/span><\/h3>\n
 Kita dapat menggunakan kode berikut untuk memilih secara acak 25%<\/strong> dari seluruh baris dalam bingkai data:<\/span><\/p>\n
 library<\/span> (dplyr)\n\n#randomly select 25% of all rows from data frame<\/span>\ndf %>% sample_frac( .25<\/span> )\n\n  team points rebounds\n1 E 15 10\n2 G 12 7\n<\/strong><\/span><\/pre>\n
 Karena kerangka data asli memiliki 8 nilai total, 25% dari 8 sama dengan 2.<\/span><\/p>\n
 Jadi, dua baris dipilih secara acak dari bingkai data.<\/span><\/p>\n

 Tutorial berikut menjelaskan cara melakukan operasi umum lainnya di dplyr:<\/span><\/p>\n
 Cara memilih kolom berdasarkan indeks menggunakan dplyr<\/a>
 Cara memilih baris pertama berdasarkan grup menggunakan dplyr<\/a>
 Cara memfilter berdasarkan beberapa kondisi menggunakan dplyr
 Cara memfilter baris yang berisi string tertentu menggunakan dplyr<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
