在R（Rstudio）中读取诸如ÆØÅ之类的特殊字符 [英] Reading special characters like ÆØÅ into R (Rstudio)

问题描述

我正在尝试读取一个CSV文件，其中包含以挪威语编写的问卷数据。因此，此文件包含字母ÆØÅ，但是R似乎不能很好地处理这些字母，它们都显示为问号。

I am trying to read a CSV file containing questionnaire data written in Norwegian. So this file contains the letters Æ Ø Å, however R does not seem to handle these letters well, they all appear as question marks.

我用它来读取数据：

data <- read.csv2("Responser - Vasket - 20.06.2013.csv")

我应该使用任何选项让R知道我有特殊字符吗？

Is there any options I should use to let R know I have special characters?

，而我正在Windows 7上使用Rstudio。

and I am using Rstudio on Windows 7.

推荐答案

您需要指定 read.csv2 的fileEncoding 参数（ not 以及（？） encoding ）。

You need to specify the fileEncoding argument to read.csv2 (not as well as (?) the encoding).

在转到R之前，最好先检查一下编码的文件正在使用文本编辑器。例如，如果您在Notepad ++中打开文件，则可以使用编码菜单查看和更改字符编码。在TextPad中，您可以从另存为..对话框中更改编码。

Before you get to R, it is a good idea to check what the encoding of the file is using a text editor. For example, if you open a file in Notepad++, the Encoding menu lets you view and change the character encoding. In TextPad, you can change the encoding from the Save As.. dialog box. Most text editors will have such a feature.

这是您需要传递给 fileEncoding 的值。您不能仅仅将文件声明为UTF-16（如果尚未创建）。这就是为什么您要发出警告。

This is the value you need to pass to fileEncoding; you can't just declare a file to be UTF-16 if it isn't already. That's why you had a warning.
