3            * R/matrix.R (termFreq): Allow reordering of control option
4            processing.

6    2011-11-17  Ingo Feinerer  <feinerer@logic.at>
7    
8            * R/reader.R (readPDF): Use tools:::pdf_info() instead of external

13    
14            * R/matrix (termFreq): Allow local option \code{bounds$local} to
15            restrict how often a term may appear in each document (generalizes
16            \code{minDocFreq}). Similarly the local option \code{wordLenghts}
17            for word length bounds (generalizes \code{minWordLength}).
18    
19            * R/matrix.R (TermDocumentMatrix.VCorpus): New global option
20            \code{bounds$global} for restricting how often a term is allowed

22    
23            * R/matrix.R (TermDocumentMatrix.VCorpus): Distinguish between
24            local options delegated internally to termFreq() and global
25            options which are processed by the term-document matrix
26            constructor itself.
