Загрузка данных в определенные папки

0 голосов
/ 02 апреля 2019

У меня есть фрейм данных с номером urls.Я пишу некоторый код, чтобы сказать R перейти на url и загрузить его.Однако я хочу быть немного организованным, поэтому я хочу сохранить urls в папке в зависимости от года, из которого он был собран.То есть у меня есть столбец в данных с именем filing_date_year.

Так что, если url был получен из year 2003, тогда я хочу сохранить url в папке с именем 2003.Однако, если год был 2010, то я хотел бы сохранить документ в папке с именем 2010.

########################################################################

У меня есть следующий код: 

library(purrr)
walk2(data_information_documents_toget$href.y, data_information_documents_toget$CIKAccNumFileDate_web_extension,
      function(x, y) {
        download.file(x, destfile = paste0("c:/USER/directory/",year_to_filter, "/", y), quiet = FALSE)
      })

, который берет из фрейма данных с именем data_information_documents_toget url, в котором находится документ href.y.Я хочу загрузить это url и сохранить его с уникальным идентификатором CIKAccNumFileDate_web_extension

Я пытаюсь добавить условие year_to_filter, которое, по сути, будет индексом, указывающим, было ли взято urlиз строки с годом 2003, затем сохраните ее в папке 2003 и т. д.

Образцы данных: 

data_information_documents_toget <- structure(list(href.y = c("https://www.sec.gov/Archives/edgar/data/1578845/000156459019003111/agn-10k_20181231.htm",

РЕДАКТИРОВАТЬ:

Если данныеназывается d и каталог выглядит следующим образом: D:/SPY_data/, затем начинается загрузка данных. 

library(purrr)
walk2(d$href.y, d$CIKAccNumFileDate_web_extension,
      function(x, y) {
        download.file(x, destfile = paste0("D:/SPY_data/", y), quiet = FALSE)
      })

Это загружает файлы в одну папку, однако я надеюсь, что файлы в нескольких папках по годам.

Вы можете попробовать это, я сначала создаю каталоги на весь год, а затем скачиваю файлы 

library(purrr)
walk(as.vector(paste0("D:/SPY_data/", d$filing_date_year)), dir.create)

walk2(d$href.y,
      paste(d$filing_date_year, d$CIKAccNumFileDate_web_extension,
            sep = "/"),
      function(x, y) {
        download.file(x, 
                      destfile = paste0("D:/SPY_data/", y),
                      quiet = FALSE)
      })
