mlogit.data() 错误:分配的数据 `ids` 必须与现有数据兼容 [英] mlogit.data() Error: Assigned data `ids` must be compatible with existing data

问题描述

我一直在努力解决这个问题，但我找不到任何解决问题的方法.希望这里有人可以提供帮助.

I have been working hours on that and I simply cannot find any solution to the problem. Hopefully someone here can help.

我正在尝试为一些具有以下结构的数据创建个人选择矩阵:

I'm trying to create a personal choice matrix for some data with the following structure:

# A tibble: 2,152 x 32
     age choice canton  lr_s dist_svp dist_fdp dist_bdp dist_cvp dist_glp dist_sp
   <dbl> <fct>  <fct>  <dbl>    <dbl>    <dbl>    <dbl>    <dbl>    <dbl>   <dbl>
 1    39 sp     GE         3       49       25       25        4       16       1
 2    67 sp     ZH         0      100       49       64        4       25       0
 3    42 svp    ZH         7        4        4        1       36        4      36

   dist_gps pid_svp pid_fdp pid_bdp pid_cvp pid_glp pid_sp pid_gps french italian
      <dbl>   <dbl>   <dbl>   <dbl>   <dbl>   <dbl>  <dbl>   <dbl>  <dbl>   <dbl>
 1        0       0       0       0       0       0      0       1      1       0
 2        9       0       0       0       0       0      1       0      0       0
 3       36       0       0       0       0       0      1       0      0       0

现在，我需要创建一个个人选择矩阵，其中包含列中 dist_*/pid_* 指示的 7 个备选方案.

Now, I need to create a personal choice matrix with the 7 alternatives that are indicated by dist_* / pid_* in the columns.

根据我的理解，这应该使用以下代码:

This should, according to my understanding, work with the following code:

work.pc <- mlogit.data(work,
                       varying = c(5:11, 12:18),
                       choice = "choice",
                       shape = "wide",
                       sep = "_")

但是，当我运行此代码时，我收到以下错误消息和一些警告消息:

However, when I run this code, I get the following Error message and a few Warning messages:

Error: Assigned data `ids` must be compatible with existing data.
x Existing data has 15064 rows.
x Assigned data has 2152 rows.
ℹ Only vectors of size 1 are recycled.
Run `rlang::last_error()` to see where the error occurred.
In addition: Warning messages:
1: Setting row names on a tibble is deprecated. 
2: Setting row names on a tibble is deprecated. 
3: Setting row names on a tibble is deprecated. 
4: Setting row names on a tibble is deprecated. 
5: Setting row names on a tibble is deprecated. 
6: Setting row names on a tibble is deprecated. 
7: Setting row names on a tibble is deprecated. 

这里有什么问题?我很感激任何帮助！我什么都试过了.

What's the issue here? I'm grateful for any help! I've tried everything.

推荐答案

问题解决:tibble work"必须转换为数据帧.

Problem solved: the tibble "work" has to be converted into dataframe.

使用后

work <- as.data.frame(work)

代码运行正常，即消除了错误消息.

the code functions properly i.e. the Error message is eliminated.
