为什么这个 csv 文件不会加载到 R mlogit 中？

Question

已解决

整个下午我都被这个问题搞得头晕目眩，我简直想不通为什么我不能在这个简单的数据集上运行 mlogit

小剪

race,horseno,place,win,
1,1,4,0,1,0.7,1,0.33,0.13,0.09,0.72,1
1,2,2,0,0.45,0.78,0.99,0.5,0.22,0.2,0.73,0.98
1,3,1,1,0.42,1,0.99,1,0.18,0.1,0.73,0.76
1,4,3,0,0.19,0.27,0.99,0.17,0.22,0.12,0.73,0.47

可以在这里找到，当我运行时，这个确切的 csv 不起作用，这就是错误。

> x <- mlogit.data(data, choice = "win", shape = "long", id.var = "race", alt.var = "horseno")
Error in `$<-.data.frame`(`*tmp*`, "id1", value = c(1L, 1L, 1L, 1L, 1L,  : 
  replacement has 22 rows, data has 26

老实说，如果有人能救我，我将不胜感激

根据你的数据我不是很了解选择情况。不过，我尝试将您的数据与 this tutorial 中的 TravelMode 数据进行比较。您的数据中的 race 似乎类似于 TravelMode 数据中的 individual，即 包含有关选择情况信息的变量的名称.所以，我假设 race 可以分配给 chid.var。这是我的试用版：

dat = read.table(text = "race,horseno,place,win,of,ppf,orf,df,jf,tf,wf,af
1,1,4,0,1,0.7,1,0.33,0.13,0.09,0.72,1

1,3,1,1,0.42,1,0.99,1,0.18,0.1,0.73,0.76
