Remove the characters at the data frame entry

I'm new at R and I am trying to remove the year of a film. 

movie_title  <- c("carrie(2013)", "cars", "lesmiserables(2012)")

For example, here I would like to delete "(2013)" from the title Carrie. So, make "carrie" instead of "carrie(2013)". And apply it to all the similar tiles in the movie_title column in the data frame.

What should I do? Thanks!

You will need to look up regex or regular expressions.

Using base r you can do this:

gsub("\\(\\d{4}\\)", "", movie_title)

With the stringr package

library(stringr)

str_remove(movie_title, "\\(\\d{4}\\)")

[1] "carrie"        "cars"          "lesmiserables"
