Anda dapat menggunakan metode berikut untuk menghitung jumlah kolom yang berjalan di R menggunakan paket dplyr<\/a> :<\/span><\/p>\n

Metode 1: Hitung jumlah kumulatif kolom<\/strong><\/span><\/p>\n

 df %>% mutate(cum_sum = cumsum(var1))\n<\/strong><\/pre>\n
 Metode 2: hitung jumlah kumulatif per kelompok<\/strong><\/span><\/p>\n
 df %>% group_by(var1) %>% mutate(cum_sum = cumsum(var2))\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan masing-masing metode dalam praktik.<\/span><\/p>\n
 Contoh 1: Hitung jumlah kumulatif menggunakan dplyr<\/strong><\/span><\/h3>\n
 Misalkan kita memiliki bingkai data berikut di R:<\/span><\/p>\n
 #create dataset\n<\/span>df <- data. frame<\/span> (day=c(1, 2, 3, 4, 5, 6, 7, 8),\n                 sales=c(7, 12, 10, 9, 9, 11, 18, 23))\n\n#view dataset\n<\/span>df\n\n  day sales\n1 1 7\n2 2 12\n3 3 10\n4 4 9\n5 5 9\n6 6 11\n7 7 18\n8 8 23\n<\/strong><\/pre>\n
 Kita dapat menggunakan kode berikut untuk membuat kolom baru yang berisi jumlah kumulatif nilai pada kolom \u201cpenjualan\u201d:<\/span><\/p>\n
 library<\/span> (dplyr)<\/span>\n\n#calculate cumulative sum of sales\n<\/span>df %>% mutate(cum_sales = cumsum(sales))\n\n  day sales cum_sales\n1 1 7 7\n2 2 12 19\n3 3 10 29\n4 4 9 38\n5 5 9 47\n6 6 11 58\n7 7 18 76\n8 8 23 99\n<\/strong><\/pre>\n
 Contoh 2: Hitung jumlah kumulatif per grup menggunakan dplyr<\/strong><\/span><\/h3>\n
 Misalkan kita memiliki bingkai data berikut di R:<\/span><\/p>\n
 #create dataset\ndf <- data. frame<\/span> (store=c('A', 'A', 'A', 'A', 'B', 'B', 'B', 'B'),\n                 day=c(1, 2, 3, 4, 1, 2, 3, 4),\n                 sales=c(7, 12, 10, 9, 9, 11, 18, 23))\n\n#view dataset\n<\/span>df\n\n  store day sales\n1 To 1 7\n2 to 2 12\n3 to 3 10\n4 to 4 9\n5 B 1 9\n6 B 2 11\n7 B 3 18\n8 B 4 23<\/span><\/span><\/strong><\/pre>\n
 Kita dapat menggunakan kode berikut untuk membuat kolom baru yang berisi jumlah kumulatif nilai pada kolom “penjualan”, yang dikelompokkan berdasarkan kolom “toko”:<\/span><\/p>\n
 library<\/span> (dplyr)<\/span>\n\n#calculate cumulative sum of sales by store\n<\/span>df %>% group_by(store) %>% mutate(cum_sales = cumsum(sales))\n\n# A tibble: 8 x 4\n# Groups: store[2]\n  store day sales cum_sales   \n1 To 1 7 7\n2 A 2 12 19\n3 To 3 10 29\n4 A 4 9 38\n5 B 1 9 9\n6 B 2 11 20\n7 B 3 18 38\n8 B 4 23 61\n<\/strong><\/pre>\n
