nzilbb.labbcat (version 1.0-1)

getMatchLabels: Gets labels of annotations on a given layer, identified by given match IDs.

Description

Gets labels of annotations on a given layer, identified by given match IDs.

Usage

getMatchLabels(
  labbcat.url,
  match.ids,
  layer.ids,
  target.offset = 0,
  annotations.per.layer = 1,
  include.match.ids = FALSE,
  page.length = 1000,
  no.progress = FALSE
)

Arguments

labbcat.url

URL to the LaBB-CAT instance

match.ids

A vector of annotation IDs, e.g. the MatchId column, or the URL column, of a results set.

layer.ids

A vector of layer IDs.

target.offset

The distance from the original target of the match, e.g.

• 0 -- find annotations of the match target itself,

• 1 -- find annotations of the token immediately after match target

• -1 -- find annotations of the token immediately before match target

annotations.per.layer

The number of annotations on the given layer to retrieve. In most cases, there's only one annotation available. However, tokens may, for example, be annotated with `all possible phonemic transcriptions', in which case using a value of greater than 1 for this parameter provides other phonemic transcriptions, for tokens that have more than one.

include.match.ids

Whether or not the data frame returned includes the original MatchId column or not.

page.length

In order to prevent timeouts when there are a large number of matches or the network connection is slow, rather than retrieving matches in one big request, they are retrieved using many smaller requests. This parameter controls the number of results retrieved per request.

no.progress

TRUE to supress visual progress bar. Otherwise, progress bar will be shown when interactive().

Value

A data frame of labels.
