Ada dua cara umum untuk melakukan join kanan di R:<\/span><\/p>\n

Metode 1: Gunakan Basis R<\/strong><\/span><\/p>\n

 merge(df1, df2, by=' column_to_join_on<\/span> ', all. y<\/span> = TRUE<\/span> )\n<\/strong><\/pre>\n
 Metode 2: gunakan dplyr<\/strong><\/span><\/p>\n
 library<\/span> (dplyr)\n\n<\/span>right_join(df1, df2, by=' column_to_join_on<\/span> ')<\/strong><\/pre>\n
 Kedua metode akan mengembalikan semua baris dari df2<\/strong> dan semua baris dengan kunci yang cocok dari df1<\/strong> .<\/span><\/p>\n
 Perlu diperhatikan juga bahwa kedua metode akan menghasilkan hasil yang sama, namun metode dplyr akan cenderung bekerja lebih cepat pada kumpulan data yang sangat besar.<\/span><\/p>\n
 Contoh berikut menunjukkan cara menggunakan masing-masing fungsi ini dalam praktik dengan bingkai data berikut:<\/span><\/p>\n
 #define first data frame\n<\/span>df1 = data. frame<\/span> (team=c('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H'),\n                 points=c(18, 22, 19, 14, 14, 11, 20, 28))\n\ndf1\n\n  team points\n1 to 18\n2 B 22\n3 C 19\n4 D 14\n5 E 14\n6 F 11\n7 G 20\n8:28 a.m.\n\n#define second data frame\n<\/span>df2 = data. frame<\/span> (team=c('A', 'B', 'C', 'D', 'L', 'M'),\n                 assists=c(4, 9, 14, 13, 10, 8))\n\ndf2\n\n  team assists\n1 to 4\n2 B 9\n3 C 14\n4 D 13\n5 L 10\n6 M 8<\/strong><\/pre>\n
 Contoh 1: Gabung kanan menggunakan Basis R<\/strong><\/span><\/h3>\n
 Kita dapat menggunakan fungsi merge()<\/strong> di basis R untuk melakukan penggabungan yang benar, menggunakan kolom ‘tim’ sebagai kolom untuk bergabung:<\/span><\/p>\n
 #perform right join using base R<\/span>\ndf3 <- merge(df1, df2, by=' team<\/span> ', all. y<\/span> = TRUE<\/span> )\n\n#view result<\/span>\ndf3\n\n  team points assists\n1 to 18 4\n2 B 22 9\n3 C 19 14\n4 D 14 13\n5 L NA 10\n6 M NA 8\n<\/strong><\/pre>\n
 Perhatikan bahwa semua baris dari df2<\/strong> disertakan dalam bingkai data akhir, namun hanya baris dari df1<\/strong> yang memiliki nama tim yang cocok yang disertakan dalam bingkai data akhir.<\/span><\/p>\n
 Contoh 2: Gabung kanan menggunakan dplyr<\/strong><\/span><\/h3>\n
 Kita dapat menggunakan fungsi right_join()<\/strong> dari paket dplyr<\/a> untuk melakukan penggabungan yang benar, menggunakan kolom ‘team’ sebagai kolom untuk bergabung:<\/span><\/p>\n
 library<\/span> (dplyr)\n\n#perform right join using dplyr<\/span> \ndf3 <- right_join(df1, df2, by=' team<\/span> ')\n\n#view result\n<\/span>df3\n\n  team points assists\n1 to 18 4\n2 B 22 9\n3 C 19 14\n4 D 14 13\n5 L NA 10\n6 M NA 8<\/strong><\/pre>\n
 Perhatikan bahwa ini sesuai dengan hasil yang kita peroleh dengan menggunakan fungsi merge()<\/strong> di basis R.<\/span><\/p>\n
