CITAN PACKAGE CHANGELOG


*******************************************************************************

2011.04-1 /2011-04-08/
   * CITAN now depends on R (>= 2.10.0), DBI and RSQLite.
   * Datafiles included: Scopus_ASJC, Scopus_SourceList -
       information on sources covered by Elsevier
       SciVerse Scopus bibliometric database and their ASJC classification
       codes. License information: this data are publicly available
       and hence no special permission is needed to redistribute them
       (information from Elsevier).
       
   New functions:
   * sqlTrim(), sqlEscapeTrim(), sqlEscape(), sqlSwitchOrNULL(),
      sqlStringOrNULL(), sqlNumericOrNULL() prepare data of various types
      for use in SQL queries.
   * dbExecQuery() - executes an SQL query and immediately frees all
      allocated resources.
   * dbBiblioConnect() - connects to a local bibliometric storage handled
      by SQLite engine.
   * dbBiblioCreate() - creates an empty local bibliometric storage.
   * dbBiblioClear() - clears a local bibliometric storage by dropping
      all tables named Biblio_* and all views named ViewBiblio_*.
   * dbBiblioDeleteAuthorsDocuments() - deletes are author, document
      and survey information from a local bibliometric storage.
   * Scopus_ImportSources - imports SciVerse Scopus covered titles and
      their ASJC codes to an empty local bibliometric storage.
   * Scopus_ReadCSV() - reads bibliography entries from a 40-column CSV file
      created e.g. with SciVerse Scopus (Complete format).
   * dbBiblioImportDocuments() - imports publications from a special 14-column
      data frame to a local bibliometric storage. Such an input may be created
      e.g. with Scopus_ReadCSV().
   * dbBiblioDescriptiveStats() - performs preliminary data analysis of data
      in a local bibliometric storage by displaying some basic descriptive
      statistics and plots.
   * dbBiblioGetCitations() - creates citation sequences for authors in
      a local bibliometric storage, that is vectors of citation counts
      of all the documents mapped to selected authors. The results may be
      restricted to a given Survey or document types.
   * dbBiblioAssess() - Calculates values of impact functions
      for a given list given citation sequences.


*******************************************************************************

2011.03-2  /2011-03-23/
   * pareto2.phirsch(), pareto2.dhirsch() - time-optimized versions
        of phirsch() and dhirsch() for the Pareto-Type II distribution.
   * pareto2.htest()        - time-optimized
        (e.g. 48.26 vs 2.72 sec. for n=25, 22.44 vs 1.40 sec. for n=10).
   * pareto2.goftest()      - minor bug fix; removed `alternative' parameter
        as ad.test() does not support it.
   * pareto2.zsestimate()   - minor bug fix; allow shape paramter 0<s<=1.
   * pareto2.mleksestimate(), discrpareto2.mleksestimate,
        discrpareto2.mlekestimate - new functions
        to find the parameter estimates for the Type II-Pareto
        distribition and its discretized version using the MLE.
   * pareto2.confint.h()    - changed method of calculation.
   * pareto2.confint.h.lower(), pareto2.confint.h.upper() - new functions
        for exact lower- and upper confidence bounds of the theoretical h-index
        given the value of a (sample) h-index.


*******************************************************************************

2011.03-1  /2011-03-02/
   * pareto2.htest.approx() - new function: Two-sample asymptotic h-test
        for equality of shape parameters for Type II-Pareto distributions
        with known scale parameter.
   * pareto2.mlekestimate() - new function to estimate the shape parameter
        of the Pareto-type II distribution using unbiased MLE.
   * pareto2.goftest()      - params 'k' and 's' added.
   * index.rp(), index.lp() - now checking param 'p' for possible flaws.
   * pareto2.zsestimate()   - now checking param 'x' for possible flaws.
   * All functions using the Pareto-type II distribution now accept
        scale parameter s>0.
   * minor bug fixes
