I got a problem with using “stop_words”.

What I tried is;

tibble(text = word_space) %>%
  unnest_tokens(output = word,
                input = text) %>%
  anti_join(stop_words) %>%
  count(word, sort = TRUE)

And the error message is;

ncol(corpus) >= 2 is not TRUE
> 

Additional info is below.

This is how “word_space” is made of;

word_space <- cam %>%
  unnest_tokens(input=value,
                output = word,
                token = "words")

word_space <- word_space %>%
  count(word, sort = T)

The “word_space” has only one column and it’s character.
This is how the “word_space” looks like;

> word_space
# A tibble: 33,592 × 1
   word     
   <chr>    
 1 hello    
 2 thank    
 3 you      
 4 for      
 5 coming   
 6 for      
 7 the      
 8 focus    
 9 group    
10 interview
# ℹ 33,582 more rows
# ℹ Use `print(n = ...)` to see more rows

Unfortunately I don’t have any idea to handle this error.
Is there anybody to give me a hand? Thanks a lot.
