- Set up a twitter API
- Let's get started with RuPaul's drag race's tweets!
- Now make your own analysis!
Before you can download data from Twitter, you need to setup your API by becoming a Twitter developer. First, to become a Twitter developer you need to have a Twitter account. Then, you can sign up here (Figure 1). Once you have signed up click on the My Apps buttom on the left panel as in Figure 2 and then click on Create a new app. You should provide a brief description about your App and a few other details. For today's workshop we set up the the Rladies App shown in Figure 3. By clicking onto your App's name you can now manage and see your settings as well as the codes that you need to get started with R. You can find the keys that you need in the Keys and Access Tokens button. Here you can find your four codes (highlighted in Figure 4) to use into R.

RuPaul's drag race is an American reality competitions showing RuPaul's search for "America's next drag superstar". Just to tease your curiosity, Figure 5 shows you all the Queens which are competing in Season 9!

The first thing to do when you want to analyse a topic using Twitter's data is to know what is or are the most useful hastag/s that can describe your questions. This means those hastags that are most commonly used when what you are interested in is tweeted. In this example we are interested into the trends of RuPaul's drag race Season 9. A little bit of research through Twitter or Goggle is needed to define a set of good hastags. For example, we found a web page listing the top hashtags for RuPaul's drag race https://top-hashtags.com/hashtag/rupaul/. For simplicity we will limit our search to two hastags and we decided to use one specific for season 9, #rpdr9, and a more general one, #rupaulsdragrace.
First, start by installing and loading all the necessary packages.
> ## Initialize functions needed for the analyses
> ## Packages that you need to setup your API in R and
> ## download twitter data
> install.packages("twitteR")
> install.packages("ROAuth")
> install.packages("RCurl")
> install.packages("RJSONIO")
>
> # Packages for sentiment analyses and wordclouds
> install.packages("RSentiment")
> install.packages("tm")
> install.packages("wordcloud")
>
> # Genral R packages for plotting and manipulating
> # data
> install.packages("tidyr")
> install.packages("dplyr")
> install.packages("ggplot2")
> install.packages("plotly")
> install.packages("stringr")

> require("RCurl")
> require("RJSONIO")
> require("tidyr")
> require("dplyr")
> require("ggplot2")
> require("plotly")
> library("stringr")
> library("knitr")
> source(file.path(dir, "score_sentiment.R"))Then setup your access keys as below. If you don't remember where to find these codes see Figure 1).
> api_key <- "yourAPIKey"
> api_secret <- "yourAPISecret"
> token <- "yourToken"
> token_secret <- "yourTokenSecret"
>
> twitteR::setup_twitter_oauth(api_key, api_secret, token,
+ token_secret)Twitter only allows you to retrieve tweets up to about two weeks before. Therefore, if you are planning to analyse some particular tweets across few weeks or months you will have to plan the downloading about every two weeks. For example, for this workshop we downloaded data on the 5th of May and on the 14th of May using the code below:
> ### Download the tweets
> # Download only English tweets
> # 5th of May
> twittes_rpdr9_1 <- twitteR::searchTwitter("#rpdr9", n = 3000, lang= "en", since= "2017-03-01")
> # 14th May
> twittes_rpdr9_2 <- twitteR::searchTwitter("#rpdr9", n = 3000, lang= "en", since= "2017-03-01")
> twittes_rpdr <- twitteR::searchTwitter("#rupaulsdragrace", n = 3000, lang= "en", since= "2017-03-01")
>
> # Save output as R objects
> saveRDS(twittes_rpdr9_2, file.path(dir,"Data","twitter_rpdr9.rds")
> saveRDS(twitter_rpdr9, file.path(dir,"Data","twitter_rpdr9_2.rds")
> saveRDS(twittes_rpdr, file.path(dir,"Data","twitter_rupoldragrace.rds")Now, read into R the two sets of tweets that we previously downloaded.
> # Load the files got from twitteR::searchTwitter
> # run three times
> twitter_rpdr9_1 <- readRDS(file.path(dir, "Data", "twitter_rpdr9.rds"))
> twitter_rpdr9_2 <- readRDS(file.path(dir, "Data", "twitter_rpdr9_2.rds"))
> twitter_rpdr <- readRDS(file.path(dir, "Data", "twitter_rupoldragrace.rds"))
> class(twitter_rpdr9_1)## [1] "list"
> # Convert the lists to data.frames
> toDF_rupol_1 <- twitteR::twListToDF(twitter_rpdr9_1)
> toDF_rupol_2 <- twitteR::twListToDF(twitter_rpdr9_2)
> toDF_rupol_3 <- twitteR::twListToDF(twitter_rpdr)Now we would like to combine the two sets of tweets and remove overlapping tweets since there is overlap in the days.
> # Time interval of the tweets dates Set 1
> min(toDF_rupol_1$created)## [1] "2017-04-26 13:22:29 UTC"
> max(toDF_rupol_1$created)## [1] "2017-05-06 00:56:42 UTC"
> # Set 2
> min(toDF_rupol_2$created)## [1] "2017-05-04 21:01:33 UTC"

> # There is a two days overlap
>
> # Combine the data.frame and remove duplicated
> # tweets
> combineTweetsDupl <- rbind(toDF_rupol_1, toDF_rupol_2,
+ toDF_rupol_3)
> duplicatedRows <- duplicated(combineTweetsDupl)
> sum(duplicatedRows)## [1] 162
> combineTweets <- combineTweetsDupl[!duplicatedRows,
+ ]
> sum(duplicated(combineTweets))## [1] 0
> colnames(combineTweets)## [1] "text" "favorited" "favoriteCount" "replyToSN"
## [5] "created" "truncated" "replyToSID" "id"
## [9] "replyToUID" "statusSource" "screenName" "retweetCount"
## [13] "isRetweet" "retweeted" "longitude" "latitude"
> # Save the clean data to file
> write.csv(combineTweets, file.path(dir, "Data", "tweets_hastags_combined.csv"),
+ row.names = FALSE)With the help of tidyr we can reorganise and manipulate the dataset. For example, we can plot the number of tweets per day.
> combineTweets <- read.csv(file.path(dir, "Data", "tweets_hastags_combined.csv"))
> colnames(combineTweets)## [1] "text" "favorited" "favoriteCount" "replyToSN"
## [5] "created" "truncated" "replyToSID" "id"
## [9] "replyToUID" "statusSource" "screenName" "retweetCount"
## [13] "isRetweet" "retweeted" "longitude" "latitude"
> toDF_rupol_daily <- combineTweets %>% tidyr::separate(created,
+ into = c("Day", "Time"), sep = " ", remove = FALSE) %>%
+ dplyr::group_by(Day) %>% dplyr::summarise(tweetsPerDay = length(text)) %>%
+ ggplot(aes(x = Day, y = tweetsPerDay)) + geom_bar(stat = "identity",
+ fill = "#88398A") + theme_bw() + theme(axis.text.x = element_text(angle = 45,
+ hjust = 1)) + coord_flip()
> toDF_rupol_daily
April 29th is the first day of our sets of tweets with a higher frequency of tweets and indeed it corresponds to RuPaul's Drag Race Episode 6 which in America was the night of April 28th (for the list of all the episodes see RuPaul's Wikia). The same thing apply for May 6th. You could also stratify every day by time and check at which time the highest number tweets was written. This is not going to be addressed here but for examples on how to deal with dates and times in R you can look at this tutorial from Berkeley https://www.stat.berkeley.edu/~s133/dates.html.
Another functionality of twitteR is to download the information about the users that wrote the the tweets. This can be done with the functions getUser() and for multiple lookups with lookupUsers() and . Of course, you are able to access user's information according to the user's permission. Therefore, you normally expect a lot of missing or fake data! The search can be done by providing on of screenNames or userIDs.

> # Create list of screenNames to look up for
> screen_names <- unique(as.character(combineTweets$screenName))There is a cap in the number of users that can be looked up in one go. The maximum is capped at 100 as stated on the Twitter Developer Documentation. Therefore, we need to look up screen_names in blocks and then combine the results.

> combine_data <- combine_data[!duplicated(combine_data),

>
> write.csv(combine_data, file.path(dir, "Data", "Users_infos_and_tweets.csv"),
+ row.names = FALSE)Now that we have combined the tweets and the user's information we can start with some analyses. For example, how many times was each queen mentioned daily? Of course, each mention could have a positive or negative connotation but nonetheless this would tell us about the overall popularity of the queen.
First, let's load the data where we saved the queen names and their twitter screen name:
> # Read in data.frame containing tweets and User's
> # infos
> combine_data <- read.csv(file.path(dir, "Data", "Users_infos_and_tweets.csv"),

We are going to do the search through the grep function and for every queen we need a unique vector of names. This is because a queen can be mentioned via her twitter name, her queen name or even her real name. For simplicity and to avoi overlap between queens we will perform the search using their drag queen names and their twitter names.

Sentiment analysis is defined as the process to computationally classify opinions from a text. Texts are sequences of qualitative information that can be seen as unstructured data. Sentiment analysis aims to classify the positivity or negativity of each sentence so that the results could be used quantitatively. To perform the following analysis we will use the package RSentiment.

> # Clean the text remove retweet entities
> some_txt <- gsub("(RT|via)((?:\\b\\W*@\\w+)+)", "",
