Wordcloud with r

When I tried the original code, it worked with older versions of R, 3.2.3 but not newer versions of R, 3.3.1 and 3.4.2. The Corpus construction was returning only numbers which were then stripped out by the rest of the code causing problems. So, I hacked together a variation of the original code based upon comments and have a working version here:

require(tm)
require(wordcloud)
require(RColorBrewer)

datain = as.data.frame(table(as.character(dataset[,1])))
words <- Corpus(VectorSource(dataset$text))

words <- tm_map(words, stripWhitespace)
words <- tm_map(words, content_transformer(tolower))
words <- tm_map(words, removeNumbers)
words <- tm_map(words, removePunctuation)
words <- tm_map(words, removeWords, stopwords("english"))
words <- tm_map(words, stemDocument)

wordcloud(words, scale=c(5,0.75), max.words=50, random.order=FALSE, rot.per=0.35, use.r.layout=FALSE, colors=brewer.pal(8, "Dark2"))

The main change is the construction of the Corpus, VectorSource(dataset) becomes VectorSource(dataset$text)

This is based upon the original PBIX file included in the original post.
