polmineR (version 0.8.0)

dispersion: Dispersion of a query or multiple queries.

Description

The method returns counts (optionally frequencies) of a query or a multiple queries in subcorpora defined by one or two s-attributes.

Usage

dispersion(.Object, ...)
# S4 method for slice
dispersion(.Object, query, s_attribute, cqp = FALSE,
  p_attribute = getOption("polmineR.p_attribute"), freq = FALSE,
  mc = FALSE, progress = FALSE, verbose = FALSE, ...)
# S4 method for partition
dispersion(.Object, query, s_attribute,
  cqp = FALSE, p_attribute = getOption("polmineR.p_attribute"),
  freq = FALSE, mc = FALSE, progress = TRUE, verbose = FALSE, ...)
# S4 method for subcorpus
dispersion(.Object, query, s_attribute,
  cqp = FALSE, p_attribute = getOption("polmineR.p_attribute"),
  freq = FALSE, mc = FALSE, progress = TRUE, verbose = FALSE, ...)
# S4 method for corpus
dispersion(.Object, query, s_attribute, cqp = is.cqp,
  p_attribute = getOption("polmineR.p_attribute"), freq = FALSE,
  mc = FALSE, progress = FALSE, verbose = FALSE, ...)
# S4 method for character
dispersion(.Object, query, s_attribute,
  cqp = is.cqp, p_attribute = getOption("polmineR.p_attribute"),
  freq = FALSE, mc = FALSE, progress = TRUE, verbose = TRUE, ...)
# S4 method for hits
dispersion(.Object, source, s_attribute, freq = FALSE,
  verbose = TRUE, ...)

Arguments

.Object

A partition object or a corpus provided by a character string.

...

Further parameters.

query

A character vector stating one or multiple queries.

s_attribute

A character vector (length 1 or 2) providing s-attributes.

cqp

If logical, whether the query is a CQP query, if it is a function that is passed in, the function will be applied to the query to guess whether query is a CQP query

p_attribute

Length one character vector, the p-attribute that will be looked up (typically 'word' or 'lemma').

freq

A logical value, whether to calculate normalized frequencies.

mc

A logical value, whether to use multicore.

progress

A logical value, whether to show progress.

verbose

A logical value, whether to be verbose.

source

The source of the evaluation the hits reported in .Object are based on, a corpus, subcorpus or partition object.

Value

depends on the input, as this is a wrapper function

A data.table.

Examples

# NOT RUN {
use("polmineR")
dispersion("GERMAPARLMINI", query = "Integration", s_attribute = "date")

test <- partition("GERMAPARLMINI", date = ".*", p_attribute = NULL, regex = TRUE)
integration <- dispersion(
  test, query = "Integration",
  p_attribute = "word", s_attribute = "date"
)
integration <- dispersion(test, "Integration", s_attribute = c("date", "party"))
integration <- dispersion(test, '"Integration.*"', s_attribute = "date", cqp = TRUE)
