sAttributes-method: Get s-attributes.

In nrauscher/corpus: Toolkit for Corpus Analysis

Description

Structural annotations (s-attributes) of a corpus provide metainformation for ranges of text. Importing XML into the Corpus Workbench (CWB) turns elements and element attributes into s-attributes. There are two uses of the sAttributes-method: If the sAttribute parameter is NULL (default), the return value is a character vector with all s-attributes. If sAttribute is the name of a specific s-attribute (i.e. a length 1 character vector), the respective s-attributes available in the corpus are returned.

Usage

## S4 method for signature 'character'
sAttributes(.Object, sAttribute = NULL, unique = TRUE,
  regex = NULL)

## S4 method for signature 'partition'
sAttributes(.Object, sAttribute = NULL)

Arguments

.Object	either a partition or a character vector specifying a CWB corpus
sAttribute	name of a specific s-attribute
unique	logical, whether to return unique values only
regex	filter return value by applying a regex

Value

a character vector

Examples

## Not run: 
  use("polmineR.sampleCorpus")
  
  sAttributes("PLPRBTTXT")
  sAttributes("PLPRBTTXT", "text_date") # dates of plenary meetings

  sAttributes(P)
  sAttributes(P, "text_name") # get names of speakers
