Reddit Extractor is an R package for extracting data out of Reddit. It allows you to:
The package can be installed directly from CRAN, using
install.packages("RedditExtractoR") or directly from GitHub
via
devtools::install_github('ivan-rivera/RedditExtractor').
Note that the latest version of this package requires R 4.1. If you have
an earlier version and are not ready to upgrade, then you can install
the earlier version of this package with
devtools::install_version("RedditExtractoR", version = "2.1.5", repos = "http://cran.us.r-project.org").
Beware that version 3+ introduces significant breaking changes!
Let’s suppose that I’d like to get the top posts from the r/cats subreddit. After
importing the package with library(RedditExtractoR) here is
how we can do it:
top_cats_urls <- find_thread_urls(subreddit="cats", sort_by="top")
str(top_cats_urls)
# 'data.frame': 999 obs. of 5 variables:
# $ date_utc : chr "2021-08-15" "2021-08-13" "2021-08-11" "2021-08-07" ...
# $ title : chr "This went on for over 5 min" "Found this friendly stray a few months back. Now she lives with me and is doing awesome but still doesn\031t ha"| __truncated__ "Let's wake up now" "Meet the kitty sisters" ...
# $ text : chr "" "" "" "" ...
# $ subreddit: chr "cats" "cats" "cats" "cats" ...
# $ comments : num 12 121 7 11 6 9 17 6 3 28 ...
# $ url : chr "https://www.reddit.com/r/cats/comments/p4zwkx/this_went_on_for_over_5_min/" "https://www.reddit.com/r/cats/comments/p3no3t/found_this_friendly_stray_a_few_months_back_now/" "https://www.reddit.com/r/cats/comments/p21kyf/lets_wake_up_now/" "https://www.reddit.com/r/cats/comments/oztuiq/meet_the_kitty_sisters/" ...Note that we simply got the top threads from a subreddit of interest.
We could also use keywords to look for threads of interest, e.g.:
find_thread_urls(keywords="cute kittens").
In some situations this could well be all you are after, but in most cases you’ll probably want to parse these URLs and retrieve their metadata and comments. Here we go:
threads_contents <- get_thread_content(top_cats_urls$url[1:2]) # for the sake of simplicity
str(threads_contents$threads) # thread metadata
# 'data.frame': 2 obs. of 14 variables:
# $ url : chr "https://www.reddit.com/r/cats/comments/p4zwkx/this_went_on_for_over_5_min/" "https://www.reddit.com/r/cats/comments/p3no3t/found_this_friendly_stray_a_few_months_back_now/"
# $ author : chr "CasterQ" "Just2063"
# $ date : chr "2021-08-15" "2021-08-13"
# $ title : chr "This went on for over 5 min" "Found this friendly stray a few months back. Now she lives with me and is doing awesome but still doesn\031t ha"| __truncated__

# $ comment_id: chr "1" "1_1" "1_1_1" "2" ...If you’d like to join comments and their parent threads, you can do this by the URL.
Sometimes you might actually be looking for subreddits rather than threads, if so, we’ve got you covered too. Let’s assume that we are trying to find subreddits about cats:
cat_subreddits <- find_subreddits("cats")
# 'data.frame': 248 obs. of 6 variables:
# $ id : chr "3gl3k" "2vi0z" "30tmh" "2tteh" ...
# $ date_utc : chr "2016-09-28" "2012-11-08" "2014-03-05" "2012-03-29" ...
# $ subreddit : chr "MemeEconomy" "Awwducational" "TwoSentenceHorror" "Justrolledintotheshop" ...
# $ title : chr "MemeEconomy" "Awwducational" "Two-Sentence Horror Stories: Bite-sized scares. " "Just Rolled Into the Shop" ...
# $ description: chr "/r/MemeEconomy is a place where individuals can buy, sell, share, make, and invest in templates freely.\n\n\nv2"| __truncated__ "Don't just waste time, learn something too!" "Give us your scariest story in two sentences (or less)!" "For those absolutely stupid things that you see people bring, roll, or toss into your place of business and the"| __truncated__ ...
# $ subscribers: num 1430743 2965466 678423 1365589 586672 ..Now you could technically feed these subreddits in a loop into the thread finder to generate a massive dataset.
Lastly, let’s suppose that you’d like to retrieve information about a particular user:
user <- "nationalgeographic"
nat_geo_user <- get_user_content(user)
str(nat_geo_user[[user]]$about)
# List of 7
# $ created_utc : chr "2017-08-24"

you could use it as:
get_user_content(c("memes","nationalgeographic"))
That’s all there is to it!
