Hello dear R members. I just came across this website: http://giladlotan.org/viz/iranelection/ Here what it is about: > ReTweet Revolution is a visual exploration of the most popular conversation > threads that were passed amongst Twitter users at the time of the events > following the Iranian elections in June of 2009. It uses an algorithm described here:

I''ve noticed that when using the form method Label, that the label text is translated to html with the first character in Upper Case and the remainder of the text string as lower case. <%= label(:country, "USA") %> becomes <label for="country_USA">Usa</ label> I can''t find any documentation on this unhelpful behavior. Is there anyway way

I have a real-world application with some complex queries that I want to convert to Arel (as part of an upgrade to Rails 3.1). So that I can understand what I''m doing before I flail around in my real app, I wrote a little sample app (just the models) with some similar associations -- one table joined with itself and more tables that join to another table, so there are some queries that

Hello everyone, in a test helper in my app I call category.id that gets the id of category in the database. However, when running RSpec I get the following error: As a parla customer /Users/saulolopes/code/parla/spec/acceptance/support/paths.rb:13: warning: Object#id will be deprecated; use Object#object_id /Users/saulolopes/code/parla/spec/acceptance/support/paths.rb:13: warning: Object#id

Hi there, I faced a weird problem doing a seemingly simple task in R. Specifically, when trying for reading an RDS file from the working directory, the following error is appeared. Code: records <- readRDS("tweets.rds") Error: Error in readRDS("tweets.rds") : error reading from connection In addition: Warning message: In readRDS("tweets.rds") : invalid or

Hi all, Is it possible to get the latitude and longitude of the location of a tweet? If I do tweets<- searchTwitter("#obama", n=200) #get tweets df <- twListToDF(tweets) #converts to data frame for ease of viewing it does not seem to be getting the location of where that tweet was posted. >From what I read from the twitter API this is possible?

Hello All, Can anyone help me solve this problem. Am trying to extract hash-tagged words from tweets downloaded from twitteR. I can extract hash-tagged words from single tweet using (stringr) str_extract_all(tweets, "#[a-z//A-Z//0-9]+")  but cannot with more than one tweet at a time except I manually remove all regular expressions and tweets numbers such as [[1]] and [1.] I want to

Wouldn't the obvious problem be that your data file is corrupted or was never created using saveRDS in the first place? Can you show us a complete example of creating and attempting to read what was just created?

Hello everyone, what''s the real difference between root_url and root_path in Rails, for example. Apparently both lead to the same route in the application.

Hola Jorge. Para poder correr las funciones del library twitteR tienes que tener varias cosas. Una cuenta en twitter y con esa cuenta inscribirte como developer en dev.twitter.com. Posterior a esto tienes que inscribir un app dentro de twitter y con las claves que se otorgan tienes que correr la función de autorizacion que ya te indicaron. Varias aclaraciones, la librería puede generar problemas

Hi all, I am trying to download as many tweets as possible (say 1000). The documentation states that the limit is 3200. However when I run police<-userTimeline('@nswpolice',n=1000) it returns random amounts. When I ran it today I got 144, yesterday it was around 300. Any thoughts? Thanks, Sachin [[alternative HTML version deleted]]

Is there a digium twitter 'user' to follow that only tweets important announcements and release information? If there is not, I think there should be. It would be highly utilitarian to get an SMS when there is an update to Asterisk, Dahdi, ADA etc, but I don't want to be bothered real-time with asteriskpbx tweets like: "Anyone trying anything cool with Asterisk over the
