GAMS Transfer R v1.4.0

  • Breaking: Symbol name uniqueness is now checked case insensitively. For
    example, it is not possible to have two different symbols named
    symbol and Symbol or SYMBOL anymore
  • Added a method Container$getSymbolNames to return the original symbol names
    for a list of symbol names of any case
  • Added a method Container$hasSymbols to check if symbol name (case insensitive)
    exists
  • Changed Container$getSymbols, Container$removeSymbols,
    Container$renameSymbol, Container$describe* and others that use
    Container$getSymbols to accept symbol names case insensitively
  • New Symbol methods hasDuplicateRecords, countDuplicateRecords, findDuplicateRecords, and dropDuplicateRecords to help debug and resolve errors with duplicate records
  • New Container methods hasDuplicateRecords, countDuplicateRecords, and dropDuplicateRecords to help find symbols that contain duplicate records that cause the Symbol to be invalid
  • Raises an exception if attempting to read a symbol that does not exist in the data source (previously symbol names were silently ignored)
  • New tests within Container$isValid() method to detect broken container references in symbols and inconsistent symbol naming between the <Container>$data field and the symbol objects
  • Breaking: Symbol records and symbol names are treated in a case insensitive manner. Symbols
    domain is not automaitcally checked
  • isValid method does not check for symbol record domain columns being factors, for duplicates, and for domain violations
  • New Symbol methods hasDomainViolations, countDomainViolations, findDomainViolations, dropDomainViolations, getDomainViolations
  • New Container methods hasDomainViolations, countDomainViolations, dropDomainViolations
  • bug fix in Alias record setter
  • bug fix in toDense() method for Symbols with domaintype other than regular
  • allowed symbol overwriting with addSet/addParameter/addVariable/addEquation/addAlias methods when everything other than records and description is unchanged
  • Added methods SpecialValues$isNA, SpecialValues$isEps, SpecialValues$isUndef, SpecialValues$isPosInf, SpcialValues$isNegInf to test for SpecialValues
  • bug fix in count* methods for multiple columns
  • The argument for where* methods changed from columns to column
  • Changing the symbol domain now changes column names of records data.frame accordingly
  • removed dependence on the package assertthat
  • automatically remove trailing whitespaces from UELs in setRecords and *UEL methods
