kwic: KWIC output / concordances

In nrauscher/corpus: Toolkit for Corpus Analysis

Description

Prepare and show concordances / keyword-in-context (kwic). The same result can be achieved by applying the kwich method on either a partition or a context object.

Usage

kwic(.Object, ...)

## S4 method for signature 'context'
kwic(.Object, meta = getOption("polmineR.meta"),
  cpos = TRUE, neighbor = NULL, verbose = FALSE)

## S4 method for signature 'partition'
kwic(.Object, query, cqp = is.cqp,
  left = getOption("polmineR.left"), right = getOption("polmineR.right"),
  meta = getOption("polmineR.meta"), pAttribute = "word",
  sAttribute = NULL, cpos = TRUE, neighbor = NULL, verbose = TRUE)

## S4 method for signature 'character'
kwic(.Object, query, cqp = is.cqp,
  left = getOption("polmineR.left"), right = getOption("polmineR.right"),
  meta = getOption("polmineR.meta"), pAttribute = "word",
  sAttribute = NULL, cpos = TRUE, neighbor = NULL, verbose = TRUE)

Arguments

.Object	a partition or context object
...	further parameters to be passed
meta	metainformation to display
cpos	logical, if TRUE, the corpus positions ("cpos") if the hits will be handed over to the kwic-object that is returned
neighbor	only show kwic if a certain word is present
verbose	logical, whether to be talkative
query	a query, CQP-syntax can be used
cqp	either logical (TRUE if query is a CQP query), or a function to check whether query is a CQP query or not (defaults to is.query auxiliary function)
left	to the left
right	to the right
pAttribute	p-attribute, defaults to 'word'
sAttribute	if provided, the s-attribute will be used to check the boundaries of the text

  kwic(
    bt, "Integration",
    left=20, right=20,
    meta=c("text_date", "text_name", "text_party")
