閱讀zTee主題文件

Question

我想zTree的對象的數據文件（問卷調）導入到R和我使用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) 

我收到以下錯誤：

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

Answer 1

我同樣的問題，和奧利弗Kirchkamp回答我：

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

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

這工作對我來說，因爲我沒有MULT相同的.sbj文件的iple版本。
