如何克服此错误tbl_vars（y）中的错误：缺少参数“y”，没有默认值？

Question

我正在尝试在2个表上执行内连接。

一个是酒店数据集，我在使用

之前已将其标记化

- rspec-core 3.6.0
- rspec-expectations 3.6.0
- rspec-mocks 3.6.0
- rspec-rails 3.6.1
- rspec-support 3.6.0

我还使用了General Inquirer Dictionary电子表格的简化版本

df1 = read.csv("chennai.csv", header = TRUE, stringsAsFactors=FALSE)
library(dplyr)
library(tidytext)

hotel <- df1 %>% unnest_tokens(word,Review_Text)
data("stop_words")
hotel <- hotel %>%
   anti_join(stop_words)
head(hotel)

      Hotel_name                          Review_Title Sentiment
 1 Accord Metropolitan Excellent comfortableness during stay         3
 2 Accord Metropolitan Excellent comfortableness during stay         3
 3 Accord Metropolitan Excellent comfortableness during stay         3
 4 Accord Metropolitan Excellent comfortableness during stay         3
 5 Accord Metropolitan Excellent comfortableness during stay         3
 6 Accord Metropolitan                   Not too comfortable         1
   Rating_Percentage  X X.1 X.2 X.3     word
 1               100 NA      NA  NA     nice
 2               100 NA      NA  NA     stay
 3               100 NA      NA  NA business
 4               100 NA      NA  NA  tourist
 5               100 NA      NA  NA  purpose
 6                20 NA      NA  NA    hotel

我试图在遇到此错误的情况下执行inner_join。

 df <- read.csv("ib.csv", header=T, stringsAsFactors=FALSE)
 dat <-subset(df, select=c(2,1))
 head(dat)

        word  Scoree
 1           A        
 2     ABANDON Negativ
 3 ABANDONMENT Negativ
 4       ABATE Negativ
 5   ABATEMENT        
 6    ABDICATE Negativ
