在R中读取zTee主题文件 [英] reading zTee subject files in R

问题描述

我想将zTree主题数据文件（quetionaire）导入R，我正在使用 zTreeSbj函数编写作者：Oliver Kirchkamp ：

I want to import zTree subjects data files (quetionaire) to R and I am using zTreeSbj function written by Oliver Kirchkamp:

files <- list.files(pattern = "*.sbj$",recursive=TRUE)
fname <- sub(".*/","",files)
sbj <- zTreeSbj(aggregate(files,list(fname),function(x) x[1])$x)

我收到以下错误：

reading  1 ...
Error in file(filename, "r", encoding = getOption("zTree.encoding")) : 
invalid 'description' argument
Called from: file(filename, "r", encoding = getOption("zTree.encoding"))    

推荐答案

我遇到了同样的问题，Oliver Kirchkamp回复了我：

I had the same problem, and Oliver Kirchkamp replied to me:

在您的情况下，您不需要汇总。简单地说：

In your case you do not need aggregate. Simply say:

files <- list.files(pattern = "*.sbj$",recursive=TRUE)
sbj <- zTreeSbj(files)

我，因为我没有相同的.sbj文件的多个版本。

That worked for me, because I did not have multiple versions of the same .sbj file.
