在R中有效地将反斜杠转换为正斜杠 [英] Efficiently convert backslash to forward slash in R

问题描述

我正在寻找一种将R中的反斜杠转换为正斜杠的有效方法。有时，我在Windows中复制目录的链接，会得到如下信息：

I am looking for an efficient way to convert back slash to forward slash in R. Sometime I copy the link of the directory in Windows and I get something like this:

C：\Users\jd\Documents\folder\file.txt

如何快速将其更改为 C：/Users/jd/Documents/folder/file.txt ？我什至无法将以上表达式理解为字符。会引发错误

How can I quickly change this to C:/Users/jd/Documents/folder/file.txt ? I cannot even read the above expression as character. It throws an error

\u，字符串中以 C：quotu开头没有十六进制数字。

"\u used without hex digits in character string starting ""C:\u".

我知道R中的TAB函数有助于快速找到位置，但是只是想知道是否还有其他解决方法。我也可以将工作目录更改为文件夹的位置。我只是在玩耍，试图将反斜杠转换为正斜杠，并没有直截了当，所以只是出于好奇而问这个。

I know TAB function in R helps to find the location fast, but was just wondering if there was any other work around. I could change the working directory to the location of folder also. I was just playing around and tried to convert backslash to forward slash and was not straight forward so asked this just because of curiosity.

推荐答案

在R中，您必须使用 \\ 转义 \ 因此，您的路径应为：

In R, you've to escape the \ with \\ So, your path should be:

x <- "C:\\Users\\jd\\Documents\\folder\\file.txt"

要做到这一点，您可以执行以下操作：

To get that, you can do:

x <- readline()

然后在提示符下粘贴您的未修改路径（按CTRL + V然后按ENTER）

then, at the prompt, paste your unmodified path (CTRL+V then ENTER)

最后，更改 \\ 到 / 的任何地方，都可以使用 gsub ，再一次转义 \ ，但两次，如下所示：

Finally, to change \\ to / everywhere, you could use gsub, once again by escaping the \, but twice, as follows:

gsub("\\\\", "/", x)
# [1] "C:/Users/jd/Documents/folder/file.txt"
