刚学习R语言，老师给的.Rdata格式的文件（我也不知道源文件是本文件还是excl文件啥的），我就打不开了~~~~(>_<)~~~~ ，载入foreign包也不行，大神帮忙看看这到底问题出在哪里了啊？该怎么解决呢？万分感谢！！
情况一：
> dfrm<-read.table("G:/课件及作业/R语言建模/Rdata for homework/example2_5.RData")
Error in make.names(col.names, unique = TRUE) :
  invalid multibyte string 1
In addition: Warning messages:
1: In read.table("G:/课件及作业/R语言建模/Rdata for homework/example2_5.RData") :
  line 1 appears to contain embedded nulls
2: In read.table("G:/课件及作业/R语言建模/Rdata for homework/example2_5.RData") :
  line 4 appears to contain embedded nulls
3: In read.table("G:/课件及作业/R语言建模/Rdata for homework/example2_5.RData") :
  incomplete final line found by readTableHeader on 'G:/璇句欢鍙婁綔涓?R璇�瑷�寤烘ā/Rdata for homework/example2_5.RData'
情况二：添加head=TRUE以后
>dfrm<-read.table("G:/课件及作业/R语言建模/Rdata for homework/example2_5.RData",head=TRUE)
Error in make.names(col.names, unique = TRUE) :
  invalid multibyte string 1
In addition: Warning messages:
1: In grepl("\n", lines, fixed = TRUE) :
  input string 1 is invalid in this locale
2: In grepl("\n", lines, fixed = TRUE) :
  input string 1 is invalid in this locale
3: In grepl("\n", lines, fixed = TRUE) :
  input string 1 is invalid in this locale
4: In read.table("G:/课件及作业/R语言建模/Rdata for homework/example2_5.RData",  :
  line 1 appears to contain embedded nulls
5: In read.table("G:/课件及作业/R语言建模/Rdata for homework/example2_5.RData",  :
  line 4 appears to contain embedded nulls
6: In read.table("G:/课件及作业/R语言建模/Rdata for homework/example2_5.RData",  :
  incomplete final line found by readTableHeader on 'G:/璇句欢鍙婁綔涓?R璇�瑷�寤烘ā/Rdata for homework/example2_5.RData'

对于*.Rdata数据格式，要使用：load("*.Rdata")，而不是read.table()函数。查看一下load()和read.table()。

再请问一下，load完以后该如何显示出来文件里面具体的数据内容啊？不好意思啊，太小白了。。万分感谢！！

建议 1：使用csv格式文件
2：搜索支持xls格式的R packages

R读取文本文档数据出现如下错误Error in make.names(col.names, unique = TRUE) :
  invalid multibyte string 18，是怎么回事呢

I understand the reason.

I found some source and other IO functions which read the source code from file. On my courses, these scripts are stored with encoding UTF-8, but the default chinese encoding for Chinese Traditional windows users are BIG5. Similar issues might be occurred for other non-English courses.

The solution is to add the argument encoding = "UTF-8", in my case, to these functions or connections. More generally, providing the default encoding or a hook before parsing might be a more robust solution.

Best,

The setting "encoding = "UTF-8" is really important in reading Chinese character. "Thank you very much!

"encoding = "UTF-8"  加了之后，line 1 appears to contain embedded nulls
