脚本从源代码加载时，无效的多字节字符崩溃（变音符/特殊字符）

问题描述

编辑：

对邮件列表中的建议Thx意识到我得到的问题与Sweave或Latex无关。这是一些与Mac OS X相关的问题。当我运行我的脚本选择全部并将它发送给R时，它就可以工作。

当我使用

<$ p $ （myplainRcode.R）

我收到错误消息如下所示

---

最后，我在Mac OS X上与ggplot2一起工作。我用R / p>

  Sweave（myfile.Rnw）
  

它可以创建所需的胶乳输出。现在基本测试工作了，我尝试获取我的真实世界文件，并在以下行崩溃：

  gl_bybranch = ddply （new_wans，。（period，Branchen），
 function（X）data.frame（Geschäftslage= mean（X $ sentiment）））
  

我想这与。（period ...）或ä有关。不幸的是，我不能更改这些标签，因为它们也用于传说中。所以，在我的代码中，这些丑陋的变音符号会出现。有没有办法在Sweave中逃脱他们？我不能相信这是问题，因为Sweave是德国人写的，可能是第二大元音字符（在土耳其后面）。

我得到的错误信息是：第195行解析器中的无效多字节字符

Thx对于任何想法提前！

解决方案

YAY！我知道了。对不起大家的噪音。我将所有三个文件（.Rnw，mysource.R，invokeSweave.R）切换为UTF-8，它终于奏效了。因此，所有在Mac上与Komodo一起工作的人都一定要将默认编码更改为UTF-8！

EDIT:

Thx to suggestions from the mailing list I realized that the problem I got has nothing to do with Sweave or Latex. It´s some Mac OS X related issue. Whenever I run my script by selecting all and sending it to R it works.

When I use

source("myplainRcode.R") 

i get the error message stated below

---

finally I got sweave working together with ggplot2 on my Mac OS X. I invoke Sweave inside R with

Sweave("myfile.Rnw")

which creates the desired latex output. Now that the basic tests work, I try to source my real world file and it crashes at the following line:

 gl_bybranch = ddply(new_wans,.(period,Branchen),
 function(X)data.frame(Geschäftslage=mean(X$sentiment)))

I guess it has either to do with the ".(period...)" or the "ä" . Unfortunately I can't change these labels because they are also used in legends. So, somewhere in my code these ugly umlauts will appear. Is there a way to escape them in Sweave? I can't believe that this is problem since Sweave is written by a German who probably have second most umlaut characters (behind Turkey).

The error message I get is: invalid multibyte character in Parser on line 195

Thx for any ideas in advance!

解决方案

YAY ! i got it. Sorry for the noise everybody. I switched all three files (.Rnw, mysource.R , invokeSweave.R) to UTF-8 it finally worked. So everybody who works with Komodo on a Mac make sure to change your default encoding to UTF-8 !
