2. Load the wordcloud package. Generate a word cloud that shows the 30 most frequently used bigrams in 1000 positive reviews (we8thereCounts[1:1000]). Generate a word cloud that shows the top 30 most frequently used bigrams in 1000 negative reviews (we8thereCounts[5166:6166]). Copy and paste the two word clouds below. Here is my example of a word cloud: > dim(we8thereCounts) > badwords=colSums(as. matrix(we8thereCounts[5166:6166,])) > wordcloud(names(badwords), badwords, max. words=30, col=badwords+1)
