Error in R term frequency analysis (TF-IDF)

I tried to run the following code with the following data:

library(dplyr)
library(janeaustenr)
library(tidytext)

book_words <- austen_books() %>%
 unnest_tokens(word, text) %>%
 count(book, word, sort = TRUE)

For this, I get this error message:

Error in count(., book, word, sort = TRUE) : 
  unused argument (sort = TRUE)

What do I have to change for the code to work?

It is possible that count from dplyr got masked from any other package loaded with having the same function count. So, use dplyr::count

austen_books() %>%
  unnest_tokens(word, text) %>% 
  dplyr::count(book, word, sort = TRUE)
# A tibble: 40,379 × 3
   book              word      n
   <fct>             <chr> <int>
 1 Mansfield Park    the    6206
 2 Mansfield Park    to     5475
 3 Mansfield Park    and    5438
 4 Emma              to     5239
 5 Emma              the    5201
 6 Emma              and    4896
 7 Mansfield Park    of     4778
 8 Pride & Prejudice the    4331
 9 Emma              of     4291
10 Pride & Prejudice to     4162
# … with 40,369 more rows

i.e. if we have loaded plyr after dplyr, it may mask some of the common functions available in dplyr

> austen_books() %>%
+   unnest_tokens(word, text) %>% 
+   plyr::count(book, word, sort = TRUE)
Error in plyr::count(., book, word, sort = TRUE) : 
  unused argument (sort = TRUE)
