# NOT RUN {
  use("polmineR.sampleCorpus")
  bt <- partition("PLPRBTTXT", text_year = "2009")
  speeches <- as.speeches(bt, sAttributeDates = "text_date", sAttributeNames = "text_name")
  
  # step-by-step, not the fastest way
  speeches <- enrich(speeches, pAttribute = "word")
  tdm <- as.TermDocumentMatrix(speeches, col = "count")
  
  # fast option (counts performed when assembling the sparse matrix)
  # tdm <- as.TermDocumentMatrix(speeches, pAttribute = "word")
  # termsToDropList <- noise(tdm)
  # whatToDrop <- c("stopwords", "specialChars", "numbers", "minNchar")
  # termsToDrop <- unlist(lapply(whatToDrop, function(x) termsToDropList[[x]]))
  # tdm <- trim(tdm, termsToDrop = termsToDrop)
# }
