CITAN 2021.11-1 (2021-11-01)

CITAN 2015.12-2 (2015-12-13)

• Various bug fixes.

CITAN 2014.12-1 (2014-12-06)

• Scopus_SourceList and Scopus_ASJC - updated (Oct 2011).
• Scopus_ImportSources - rewritten, optimized.
• Scopus_ReadCSV() - rewritten, allows other formats than 40 column CSVs.
• lbsImportDocuments() - rewritten, Sources are identified by Title (instead of ISSN, which is not available in Scopus ‘Citations only’ format), surnameFirstnameCommaSeparated parameter (defaults FALSE for backward compatibility), author names are converted to upper case while adding.
• lbsCreate() - new RDBS scheme (Biblio_Citations added, Biblio_Languages and Biblio_Countries dropped, allow for nondestructive Author merging - AuthorGroup field)
• Many functions have been moved to the 'agop' package, dependency added.

CITAN 2011.08-1 (2011-08-12)

• Documentation cleanup.

CITAN 2011.05-1 (2011-05-15)

• CITAN now depends on hash.
• discrpareto2.goftest() - goodness-of-fit test for a discrete Pareto-Type II distribution.
• lbsTidy() - new function that makes some consistency checks on the DB.
• sqlNumericOrNULL, sqlStringOrNULL, sqlSwitchOrNULL - now accept more than one element at a time.
• lbsGetInfoAuthors(), lbsGetInfoDocuments() - now allow large result sets.
• Scopus_ImportSources() - time-optimized (15% faster).
• lbsFindDuplicateTitles() - bug fixed: incorrect author count for aggressiveness>=1.
• lbsDescriptiveStats() - bug fixed: incorrect document count for 1<=which<=5.

CITAN 2011.04-2 (2011-04-23)

• CITAN now depends on RGtk2.
• Case-insensitive ISSN, UniqueId, Language and authors' Names matching in lbsImportDocuments().
• 'verbose' mode in lbsImportDocuments(), Scopus_ImportSources() now displays a dialog window.
• lbsCreate() - minor improvements in SQL queries for Local Bibliometric Storage creation.
• 'warnDuplicateTitles' param removed from lbsImportDocuments().
• Function name cleanup: dbBiblio* -> lbs* (CHANGELOG updated). New functions:
• lbsSearchAuthors() - finds authors meeting given criteria.
• lbsSearchDocuments() - finds documents meeting given criteria.
• lbsGetInfoAuthors() - retrieves basic information on given authors.
• lbsGetInfoDocuments() - retrieves information on given documents.
• lbsFindDuplicateTitles() - suggests documents to be deleted (EXPERIMENTAL algorithm implemented).
• lbsFindDuplicateAuthors() - suggests authors to be merged (EXPERIMENTAL algorithm implemented).
• lbsDeleteDocuments() - deletes given documents.
• lbsMergeAuthors() - merges given authors.

CITAN 2011.04-1 (2011-04-09)

• 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.
• lbsConnect() - connects to a local bibliometric storage handled by SQLite engine.
• lbsCreate() - creates an empty local bibliometric storage.
• lbsClear() - clears a local bibliometric storage by dropping all tables named Biblio_* and all views named ViewBiblio_*.
• lbsDeleteAllAuthorsDocuments() - 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).
• lbsImportDocuments() - 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().
• lbsDescriptiveStats() - performs preliminary data analysis of data in a local bibliometric storage by displaying some basic descriptive statistics and plots.
• lbsGetCitations() - 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.
• lbsAssess() - Calculates values of impact functions for a given list given citation sequences.

CITAN 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 parameter 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.

CITAN 2011.03-1 (2011-03-04)

• 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.
