CHANGES IN qdap VERSION 2.1.0

BUG FIXES

  • new_project did not copy the .Rprofile over into the new project. This has
    been fixed. Reference issue #184.
  • sentiment_frame coerced words to factor. stringsAsFactors = FALSE has
    been added to prebent this.
  • polarity did not work on > 1 grams due to a bug in sentiment_frame
    converting character to factor (chewth). See GitHub issue #185 for details.

NEW FEATURES

  • unique_by added to allow the user to find terms unique to individual
    elements of a grouping variable.
  • build_qdap_vignette replaces the temporary place holder version of the
    Introduction to qdap vignette. This function will replace the (1) HTML,
    (2) source, & (3) R code found in browseVignettes(package = 'qdap').

MINOR FEATURES

  • sub_holder picks up a alpha.type argument that allows the user to specify
    whether alpha or numeric keys should be used.
  • replace_number picks up a remove argument that removes numbers from text.

IMPROVEMENTS

  • qheat becomes a generic method. This means some of the internal function
    class checking has been moved to individual methods for those classes.
    Additionally, qheat now works with logical matrices/data.frames.
  • The tm package compatibility functions have been renamed in a more R-ish
    way and take the form of generic methods for specific classes. For example,
    df2tm_corpus becomes as.Corpus. Here is a complete list of changes:
    • df2tm_courpus is now as.Corpus
    • tm_corpus2df is now as.data.frame
    • as.wfm is now a generic method
    • tm_corpus2wfm is now as.wfm
    • tm2qdap is now as.wfm
    • tdm is now as.tdm or as.TermDocumentMatrix
    • dtm is now as.dtm or as.DocumentTermMatrix

CHANGES

  • colsplit2df and colpaste2df no longer convert character columns to factor.
  • df2tm_corpus is deprecated. It will be removed in a subsequent version of
    qdap. Use as.Corpus instead.
  • tm_corpus2df is deprecated. It will be removed in a subsequent version of
    qdap. Use as.data.frame instead.
  • tm2qdap is deprecated. It will be removed in a subsequent version of
    qdap. Use as.wfm instead.
  • tm_corpus2wfm is deprecated. It will be removed in a subsequent version of
    qdap. Use as.wfm instead.
  • tdm is deprecated. It will be removed in a subsequent version of qdap.
    Use as.tdm or as.TermDocumentMatrix instead.
  • dtm is deprecated. It will be removed in a subsequent version of qdap.
    Use as.dtm or as.DocumentTermMatrix instead.
  • The Introduction to qdap .Rmd vignette has been moved to an internal
    directory. The HTML version is not built by default. THis saves CRAN space
    and time checking the package source. The file has been replaced with a
    temporary place holder that contains instructions for building the actual
    vignette. The user may also use the build_qdap_vignette directly.
  • qdap incorporates the chanegs from the tm package version: 0.6:
    http://cran.r-project.org/web/packages/tm/news.html Reference issue #187.
