count-method: Get counts.

In nrauscher/corpus: Toolkit for Corpus Analysis

Description

Count number of occurrences of a query (CQP syntax may be used) or, if query is NULL (default), of all tokens.

Usage

count(.Object, ...)

## S4 method for signature 'partition'
count(.Object, query = NULL, cqp = is.cqp,
  id2str = TRUE, pAttribute = getOption("polmineR.pAttribute"),
  mc = getOption("polmineR.cores"), verbose = TRUE, progress = FALSE)

## S4 method for signature 'partitionBundle'
count(.Object, query, pAttribute = NULL,
  freq = FALSE, total = T, mc = F, progress = T, verbose = FALSE)

## S4 method for signature 'character'
count(.Object, query = NULL,
  pAttribute = getOption("polmineR.pAttribute"), verbose = TRUE)

## S4 method for signature 'vector'
count(.Object, corpus, pAttribute)

Arguments

.Object	a "partition" or "partitionBundle" object, or a character vector (length 1) providing the name of a corpus
...	further parameters
query	a character vector (one or multiple terms to be looked up), 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)
id2str	logical, whether to add rownames (only if query is NULL)
pAttribute	the p-attribute(s) to use
mc	logical, whether to use multicore (defaults to FALSE)
verbose	logical, whether to be verbose
progress	logical, whether to show progress
freq	logical, if FALSE, counts will be reported, if TRUE, frequencies
total	defaults to FALSE, if TRUE, the added value of counts (column: TOTAL) will be amended to the data.table that is returned
corpus	name of CWB corpus

Value

a "data.table"

Examples

## Not run: 
\dontrun{
  use("polmineR.sampleCorpus")
  debates <- partition("PLPRBTTXT", list(text_id=".*"), regex=TRUE)
  x <- count(debates, "Arbeit") # get frequencies for one token
  x <- count(debates, c("Arbeit", "Freizeit", "Zukunft")) # get frequencies for multiple tokens
  x <- count("PLPRBTTXT", c("Migration", "Integration"), "word")

  debates <- partitionBundle(
    .Object="PLPRBTTXT",
    def=list(text_date=sAttributes("PLPRBTTXT", "text_date")),
    regex=TRUE, mc=FALSE, verbose=FALSE
  )
  aiu <- count(debates, c("Arbeit", "Integration", "Umwelt"))
