Minimum LaBB-CAT version 20230224.1731

Enhancements

  • getMatches replaces participant.ids and transcript.types parameters with participant.expression and transcript.expression parameters, in line with the underlying API, and allowing more flexibility with queries.
  • getMatches parameter aligned is now deprecated, please set anchor.confidence.min = 50 instead
  • getMatches parameter anchor.confidence.min now filters out results, instead of just returning NA for offsets below the minumum confidence. To return all results and offsets, regardless of confidence, set anchor.confidence.min = 0.
  • processWithPraat’s window.offset parameter no longer has a default value, and includes more thorough documentation, to ensure callers are aware of the parameter’s implications.

New functions:

  • labbcatVersionInfo - gets version information of all components of LaBB-CAT
  • Helper functions for formulating the new participant.expression and transcript.expression parameters of getMatches:
    • expressionFromIds : expression based on a list of IDs
    • expressionFromAttributeValue : expression based on a list of possible attribute values
    • expressionFromAttributeValues : expression based on a list of possible attribute values, for attributes that can have multiple values
    • expressionFromTranscriptTypes : expression based on a list of possible transcript types
  • Manage participant records
    • getParticipant : Gets ID and participant attribute values for a single participant.
    • saveParticipant : Saves participant data (supports creating and renaming participants).
    • deleteParticipant : Deletes a single participant record.
    • renameParticipants : Batch rename participants.

Minimum LaBB-CAT version 20230202.1600

New functions:

  • countMatchingAnnotations and getMatchingAnnotations : Retrieve individual annotations that match a pattern expression.

  • getFragmentAnnotations: Returns all tokens in given transcripts on given layers between start/end times.

Enhancements

  • getMedia now downloads the media and returns the file name, rather than returning the URL.
  • getMatches accepts a string as a pattern, and assumes it’s a space-delimited orthography layer search.
  • getMatches now has anchor.confidence.min parameter, to allow retrieval of start/end times that have low confidence.
  • getMatchLabels and getMatchAlignments now return NA rather than empty strings.
  • getTranscriptIdsInCorpus, getTranscriptIdsWithParticipant, and *getTranscriptIds now return a character vector whether there are results or not.
  • countAnnotations and getAnnotations now has max.ordinal parameter, to allow retrieval of only the first word tag annotations in a transcript.
