Shiny Application

Best Spanish Books Word Cloud

Coursera Developing Data Products

There is some objectives to be done with this project:

• Use Shiny to do an application easy, simple, and using the concepts learned in the class.
• Develop a useful application for my own working specialization (Twitter analysis)

I use the libraries tm and wordcloud to analize Twiiter hashtags, but it is not possible to acces to the Twitter API online without showing my credentials, so I decide to use some public documents, as the best Spanish Books ever wroten.

Loading the Libraries:

library(tm)
library(wordcloud)

Loading the book:

text <- readLines("../lazarillo.txt", encoding="UTF-8")

Generating the Corpus:

myCorpus = Corpus(VectorSource(text))

Then doing several transformations and preparing the data for the word cloud generation.
