Great article. I had to make a few changes to run the sample under Linux: Line 7 :exe <- "/usr/bin/pdftotext" Line 12: system(paste("open", filetxt)) Also had to ensure that the tm, wordcloud and Rstem packages were installed using: install.packages("wordcloud") install.packages("tm") install.packages("Rstem", repos = "http://www.omegahat.org/R")
