如何在R中正確寫入csv或文本文件

Question

我正在嘗試在R中保存csv文件或文本文件。

一欄中有段落，其中有逗號，因此在我撰寫時；

write.table(x, file = "D:/text.csv", sep = ",", row.names = FALSE)

y <- read.csv(file = "D:/text.csv")

它寫入文件，但是當我讀入文件時，從50行增加到57行。 我知道這可能是因為sep = ","參數，我可以將其更改為“ |” 但是這些文件確實很大，並且text列中可能包含許多不同的字符，但不能使用sep工作。

我該如何克服這個問題？

Answer 1

首先將文件轉換為data.frame並嘗試

write.csv(df, file = 'df.csv', row.names = F)

然后文件將存儲在您的工作目錄中

Answer 2

怎么樣？

library(data.table)
fwrite(as.data.table(x), "text.csv")

使用fread()將其讀回。
