How to separate title from desc (scraping data IMDB-Coming Soon Movie)

okey try to run this code from you

library(tidyverse)
library(rvest)
library(reprex)
library(stringr)


url = "https://www.imdb.com/movies-coming-soon/?ref_=nv_mv_cs_4"

# get list of film coming soon
coming_soon <- url %>%
  read_html() %>%
  html_nodes(".list_item")

# create a table to contain information: one line per film
coming_movies <- tibble::tibble(
  
  # get the title (unique)
  title = coming_soon %>% 
    html_node(".overview-top h4[itemprop='name'] a") %>% 
    html_text() %>%
    str_trim(),
  
  # get the genre (several per film)
  genre = coming_soon %>%
    # use purrr::map to get one list per film (otherwise html_nodes gets you a vector too big)
    
    map(~ html_nodes(.x, ".cert-runtime-genre span[itemprop='genre']") %>% 
          html_text()),
  
  # get time in min of the film if any
  time_in_min = coming_soon %>%
    html_node("time") %>%
    html_text() %>%
    
  # parse the number
    parse_number() %>%
    as.integer(),
  
  # get the description (unique)
  description = coming_soon %>%
    html_node(".outline[itemprop='description']") %>%
    html_text() %>%
    
  # trim whitespace and newlines on both sides
    str_trim(),
  
  # get the directors (several possible per film)
  director = coming_soon %>%
    map(~ html_nodes(.x, ".txt-block span[itemprop='director'] span[itemprop='name'] a") %>% html_text()),
  
  # get the starring actos (several possible per film)
  stars = coming_soon %>%
    map(~ html_nodes(.x, ".txt-block span[itemprop='actors'] span[itemprop='name'] a") %>% html_text())) %>%
  
  # extract year from the title
  mutate(
    year = str_extract(title, "\\(\\d{4}\\)") %>%str_remove_all("[\\(\\)]"),
    title = str_remove(title, "\\(\\d{4}\\)$") %>% str_trim()
  )

and still error, and this error is

Error in mutate_impl(.data, dots) : 
  Evaluation error: could not find function "str_remove_all".
Error: object 'coming_movies' not found

thank you for help me sir, and please help me again for my understanding
