如何在R / Rstudio中逐行阅读文本文件？

Question

假设我有一个凌乱的文本文件，例如以下

Today is a good
day, but I feel very tired. It seems like it is
going to rain pretty soon.

我想将txt文件作为字符向量读入R中，就像在原始文本文件中一样。换句话说，我希望字符向量的第一个元素是第一行，字符向量的第二个元素是第二行，如下所示

char_vector[1] = "Today is a good"
char_vector[2] = "day, but I feel very tired. It seems like it is"
char_vector[3] = "going to rain pretty soon."

我已经尝试过read.table和read.csv，但总是有些行连接在一起作为一行。有办法解决这个问题吗？

Answer 1

char_vector <- readLines(filename)

 txt <- "Today is a good
 day, but I feel very tired. It seems like it is
 going to rain pretty soon."

 readLines(textConnection(txt) )
#   ---- teh screen output of three distinct character elements
[1] "Today is a good"                                
[2] "day, but I feel very tired. It seems like it is"
[3] "going to rain pretty soon."                    

char_vector <- readLines(textConnection(txt))

char_vector[1]
#[1] "Today is a good"

Answer 2

扫描可以做到这一点。

scan( file="myfile.txt", what=character() ) 

Answer 3

您可以使用readLines功能。
