Anda dapat menggunakan fungsi cumsum()<\/strong> basis R untuk dengan mudah menghitung jumlah kumulatif vektor nilai numerik.<\/span><\/span><\/p>\n

Tutorial ini menjelaskan cara menggunakan fungsi ini untuk menghitung jumlah kumulatif suatu vektor serta cara memvisualisasikan jumlah kumulatif.<\/span><\/p>\n

Cara menghitung jumlah kumulatif dalam R<\/strong><\/span><\/h3>\n

Kode berikut menunjukkan cara menghitung jumlah kumulatif penjualan untuk perusahaan tertentu selama 15 kuartal penjualan:<\/span><\/p>\n

 #create dataset<\/span>\ndata <- data.frame(quarter=1:15,\n                   sales=c(1, 2, 2, 5, 4, 7, 5, 7, 6, 8, 5, 9, 11, 12, 4))\n\n#create new column in dataset that contains cumulative sales<\/span>\ndata$cum_sales <- cumsum<\/span> (data$sales)\n\n#view dataset<\/span>\ndata\n\n   quarter sales cum_sales\n1 1 1 1\n2 2 2 3\n3 3 2 5\n4 4 5 10\n5 5 4 14\n6 6 7 21\n7 7 5 26\n8 8 7 33\n9 9 6 39\n10 10 8 47\n11 11 5 52\n12 12 9 61\n13 13 11 72\n14 14 12 84\n15 15 4 88\n<\/strong><\/pre>\n
 Nilai yang ditampilkan pada kolom cum_sales<\/strong> mewakili total penjualan hingga dan termasuk kuartal tersebut. Misalnya, penjualan kumulatif untuk kuartal 5 dihitung sebagai berikut: 1+2+2+5+4 = 14<\/strong> .<\/span><\/p>\n
 Cara memvisualisasikan jumlah berjalan di R<\/strong><\/span><\/h3>\n
 Setelah kita menghitung penjualan kumulatif, kita dapat membuat diagram garis sederhana berbasis R untuk memvisualisasikan penjualan kumulatif per kuartal:<\/span> <\/p>\n
 plot(data$cum_sales, type=' l<\/span> ', xlab=' Quarter<\/span> ', ylab=' Cumulative Sales<\/span> ')\n<\/strong><\/pre>\n
\"Bagan<\/p>\n
 Alternatifnya, kita bisa menggunakan pustaka visualisasi R ggplot2<\/a> untuk membuat grafik garis yang sama:<\/span> <\/p>\n
 library<\/span> (ggplot2)\n\nggplot(data, aes(x=quarter, y=cum_sales)) +\n  geom_line() +\n  labs(x=' Quarter<\/span> ', y=' Cumulative Sales<\/span> ')<\/strong> <\/pre>\n
