試圖快速進入以下頁面上MTA旋轉門數據：EOF錯誤？

http://web.mta.info/developers/turnstile.html

我已經打算通過頁碼循環運行的fread或download.file來存儲數據和綁定，但在一些我得到的文件和錯誤。這裏有兩個例子，一個可行，一個不可行。我注意到第二個文件看起來有點不同：

test_mta_works = fread("http://web.mta.info/developers/data/nyct/turnstile/turnstile_161224.txt", sep = ',') 

test_mta_wont_work = fread("http://web.mta.info/developers/data/nyct/turnstile/turnstile_140419.txt", sep = ',')

錯誤我收到的第二個：

Error in fread("http://web.mta.info/developers/data/nyct/turnstile/turnstile_140419.txt", : 
    Expected sep (',') but new line, EOF (or other non printing character) ends field 12 when detecting types from point 0: A002,R051,02-00-00,04-18-14,16:00:00,REGULAR,004575433,001558298,04-18-14,20:00:00,REGULAR,004575838,001558374

任何想法的問題可能是和/或如何解決這個問題？我嘗試使用fill = T，但它造成了數據問題。

謝謝！

使用補= T我得到輸出中爲以下時：

當使用'fill = T'時，您對數據有什麼問題？我能夠使用'fill'參數讀取數據，它對我來說看起來很好。 – krish

添加上面的輸出作爲編輯 – LoF10

test_mta_wont_work = fread（「http://web.mta.info/developers/data/nyct/turnstile/turnstile_140419.txt」，sep ='，'，fill = TRUE，na.strings =「」，NA） – krish

使用na.strings作爲參數fread

test_mta_wont_work = fread("http://web.mta.info/developers/data/nyct/turnstile/turnstile_140419.txt", sep = ',', fill = TRUE, na.strings = "",NA) 

head(test_mta_wont_work)
