To generate word clouds, you need to download thewordcloudpackage in R as well as theRcolorBrewerpackage for the colours. Note that there is also awordcloud2package, with a slightly different design and fun applications. I will show you how to use both packages. install.packages("wordcloud")...
First we need to load up the packages and our data: library(wordcloud) library(RColorBrewer) conventions <- read.table("conventions.csv", header = TRUE, sep = ",") And then we can get to using thewordcloudlibrary to produce our clouds in R: png("dnc.png") wordcloud(conventions$wordp...

Creating word clouds requires at least five main text-mining steps (described in my previous post). All theses steps can be performed with one line R code using rquery.wordcloud() function described in the next section. R tag cloud generator function : rquery.wordcloud The source code...
The 5 main steps to create word clouds in R Step 1: Create a text file In the following examples, I’ll process the “I have a dream speech” from “Martin Luther King” but you can use any text you want : Copy and paste the text in a plain text file (e.g : ml.t...

The previous two word clouds used only one additional argument, 'random.order', However, there are other arguments that can be used. We will now create the word cloud by changing the other arguments, which is done in the lines of code below. set.seed(100) wordcloud(words = dat$word, ...
In this article, I will show you how to use text data to build word clouds in R. We will use a dataset containing around 200k Jeopardy questions. The dataset can be downloaded here (thanks to reddit user trexmatt for providing the dataset). We will require three packages for this: tm,...
A word cloud is a visually prominent presentation of “keywords” that appear frequently in text data. The rendering of keywords forms a cloud-like color picture, so that you can appreciate the main text data at a glance. You can see many interesting word clouds on the Internet, as follows...
Have been playing around with the R Visuals Preview feature creating word clouds and have run into some issues. Was wondering if anyone else was seeing what I was seeing. When you create an R visualization, you currently have to drag one field into the visual in order to get the sc...
