加载或查看 pdata.frame 时出现问题（无法将 class“"pseries"”强制转换为 data.frame）
Issue when loading or viewing a pdata.frame (cannot coerce class ""pseries"" to a data.frame)
我对特定数据集有如下问题：
1) 我加载 table：
Regression_990_DT<-fread("DATASET FINALE PER REGRESSIONE 990.R")
2)我用它来分配一个pdata.frame:
mypanel<- pdata.frame(Regression_990_DT, index = c("Individual","Year"), drop.index = FALSE)
当我尝试从环境中查看 "mypanel" 时，我得到
View(mypanel)
Error in View : cannot coerce class ""pseries"" to a data.frame
奇怪的是，如果我使用 head 函数，我可以看到 "mypanel":
head(mypanel)

但是如果我在 plm 函数中使用 "mypanel"，我会再次遇到类似的错误。

如果我处理包 "foregin" 中的犯罪数据，则一切正常。我注意到两个数据集之间的唯一区别（除了我准备了第一个数据集之外）如下：
class(Regression_990_DT)
[1] "data.table" "data.frame"
同时
data(Crime)
class(Crime)
[1] "data.frame"
将 "Regression_990_DT" 转换为 data.frame 无法解决我的问题。问题的原因是什么，我该如何解决？如果我需要提供任何其他信息，请告诉我。
-edit：根据要求，这是
获得的 Regression_990_DT 的较短版本
smallRegression_DT<-Regression_990_DT[c(1:150),]

据我所知：这是由于一列 Expenditure 包含 class integer64，其中 pdata.frame 打嗝。
尝试将此列转换为 numeric。
我对特定数据集有如下问题：
1) 我加载 table：
Regression_990_DT<-fread("DATASET FINALE PER REGRESSIONE 990.R")
2)我用它来分配一个pdata.frame:
mypanel<- pdata.frame(Regression_990_DT, index = c("Individual","Year"), drop.index = FALSE)
当我尝试从环境中查看 "mypanel" 时，我得到
View(mypanel)
Error in View : cannot coerce class ""pseries"" to a data.frame
奇怪的是，如果我使用 head 函数，我可以看到 "mypanel":
head(mypanel)

但是如果我在 plm 函数中使用 "mypanel"，我会再次遇到类似的错误。

如果我处理包 "foregin" 中的犯罪数据，则一切正常。我注意到两个数据集之间的唯一区别（除了我准备了第一个数据集之外）如下：
class(Regression_990_DT)
[1] "data.table" "data.frame"
同时
data(Crime)
class(Crime)
[1] "data.frame"
将 "Regression_990_DT" 转换为 data.frame 无法解决我的问题。问题的原因是什么，我该如何解决？如果我需要提供任何其他信息，请告诉我。
-edit：根据要求，这是
获得的 Regression_990_DT 的较短版本smallRegression_DT<-Regression_990_DT[c(1:150),]
mypanel<-pdata.frame(smallRegression_DT,index=c("Individual","Year"),drop.index = FALSE)
