Anda dapat menggunakan salah satu metode berikut untuk mengurangi jumlah jam tertentu dari satu jam di R:<\/span><\/p>\n

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

 #create new column that subtracts 4 hours from time\n<\/span>df$subtract4 <- df$time - ( 4<\/span> * 3600<\/span> )\n<\/strong><\/pre>\n
 Metode 2: Gunakan paket Lubridate<\/strong><\/span><\/p>\n
 library<\/span> (lubridate)\n\n#create new column that subtracts 4 hours from time\n<\/span>df$subtract4 <- df$time - hours( 4<\/span> )\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan setiap metode dengan kerangka data berikut:<\/span><\/p>\n
 #create data frame\n<\/span>df <- data. frame<\/span> (time=as. POSIXct<\/span> (c('2022-01-03 08:04:15', '2022-01-05 14:04:15',\n                                   '2022-01-05 20:03:53', '2022-01-06 03:29:13',\n                                   '2022-01-06 06:15:00', '2022-01-07 10:48:11'),\n                                   format='%Y-%m-%d %H:%M:%OS'),\n                 sales=c(130, 98, 240, 244, 174, 193))\n\n#view data frame\n<\/span>df\n\n                 time sales\n1 2022-01-03 08:04:15 130\n2 2022-01-05 14:04:15 98\n3 2022-01-05 20:03:53 240\n4 2022-01-06 03:29:13 244\n5 2022-01-06 06:15:00 174\n6 2022-01-07 10:48:11 193\n<\/strong><\/pre>\n
 Catatan<\/strong> : Untuk menambahkan waktu pada suatu tanggal, cukup ganti tanda pengurangan dengan tanda penjumlahan pada salah satu rumus di atas.<\/span><\/p>\n
 Contoh 1: Mengurangi Jam dari Waktu Menggunakan Basis R<\/strong><\/span><\/h2>\n
 Kode berikut menunjukkan cara membuat kolom baru bernama subtract4<\/b> yang mengurangi empat kali dari setiap nilai di kolom waktu<\/strong> :<\/span><\/p>\n
 #create new column that subtracts 4 hours from time<\/span>\ndf$subtract4 <- df$time - ( 4<\/span> * 3600<\/span> )\n\n#view updated data frame\n<\/span>df\n\n                 time sales subtract4\n1 2022-01-03 08:04:15 130 2022-01-03 04:04:15\n2 2022-01-05 14:04:15 98 2022-01-05 10:04:15\n3 2022-01-05 20:03:53 240 2022-01-05 16:03:53\n4 2022-01-06 03:29:13 244 2022-01-05 23:29:13\n5 2022-01-06 06:15:00 174 2022-01-06 02:15:00\n6 2022-01-07 10:48:11 193 2022-01-07 06:48:11<\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa nilai pada kolom pengurangan4<\/b> yang baru sama dengan nilai pada kolom waktu<\/b> dengan pengurangan empat jam.<\/span><\/p>\n
 Catatan<\/strong> : Kita menggunakan (4*3600) dalam rumusnya karena nilai waktu disimpan sebagai detik di R. Karena ada 3600 detik dalam satu jam, kita perlu mengalikan 4 dengan 3600 untuk mengurangi 4 jam.<\/span><\/span><\/p>\n
 Contoh 2: Kurangi jam dari waktu menggunakan paket Lubridate<\/strong><\/span><\/h2>\n
 Kode berikut menunjukkan cara menggunakan fungsi jam()<\/strong> dari paket lubridate<\/a> untuk membuat kolom baru bernama subtract4<\/b> yang mengurangi empat jam dari setiap nilai di kolom waktu<\/strong> :<\/span><\/p>\n
 library<\/span> (lubridate)<\/span>\n\n#create new column that subtracts 4 hours from time\n<\/span>df$subtract4 <- df$time - hours( 4<\/span> )\n\n#view updated data frame\n<\/span>df\n\n                 time sales subtract4\n1 2022-01-03 08:04:15 130 2022-01-03 04:04:15\n2 2022-01-05 14:04:15 98 2022-01-05 10:04:15\n3 2022-01-05 20:03:53 240 2022-01-05 16:03:53\n4 2022-01-06 03:29:13 244 2022-01-05 23:29:13\n5 2022-01-06 06:15:00 174 2022-01-06 02:15:00\n6 2022-01-07 10:48:11 193 2022-01-07 06:48:11<\/span><\/span><\/strong><\/pre>\n
 Perhatikan bahwa nilai pada kolom pengurangan4<\/b> yang baru sama dengan nilai pada kolom waktu<\/b> dengan pengurangan empat jam.<\/span><\/p>\n
 Perhatikan bahwa metode ini memberikan hasil yang sama dengan metode basis R.<\/span><\/span><\/p>\n
