cooccurrences: Get cooccurrence statistics.

Description

Get cooccurrence statistics.

Usage

cooccurrences(.Object, ...)
# S4 method for character
cooccurrences(.Object, query = NULL, cqp = is.cqp,
  pAttribute = getOption("polmineR.pAttribute"), sAttribute = NULL,
  left = getOption("polmineR.left"), right = getOption("polmineR.right"),
  stoplist = NULL, positivelist = NULL, keep = NULL, cpos = NULL,
  method = "ll", mc = getOption("polmineR.mc"), verbose = FALSE,
  progress = FALSE)
# S4 method for partition
cooccurrences(.Object, query, cqp = is.cqp,
  left = getOption("polmineR.left"), right = getOption("polmineR.right"),
  pAttribute = getOption("polmineR.pAttribute"), sAttribute = NULL,
  stoplist = NULL, positivelist = NULL, keep = NULL, method = "ll",
  mc = FALSE, progress = TRUE, verbose = FALSE, ...)
# S4 method for context
cooccurrences(.Object, method = "ll", verbose = FALSE)
# S4 method for partitionBundle
cooccurrences(.Object, query,
  mc = getOption("polmineR.mc"), ...)

Arguments

.Object

a partition object, or a character vector with a CWB corpus

...

further parameters that will be passed into bigmatrix (applies only of big=TRUE)

query

query, may by a character vector to match a token, or a CQP query

cqp

defaults to is.cqp-function, or provide TRUE/FALSE, relevant only if query is not NULL

pAttribute

the pAttribute of the tokens/the query

sAttribute

if provided, it will be checked that cpos do not extend beyond the region defined by the s-attribute

left

no of tokens and to the left of the node word

right

no of tokens to the right of the node word

stoplist

exclude a query hit from analysis if stopword(s) is/are in context (relevant only if query is nut NULL)

positivelist

character vector or numeric vector: include a query hit only if token in positivelist is present. If positivelist is a character vector, it is assumed to provide regex expressions (incredibly long if the list is long) (relevant only if query is nut NULL)

keep

list with tokens to keep

cpos

integer vector with corpus positions, defaults to NULL - then the corpus positions for the whole corpus will be used

method

statistical test to use (defaults to "ll")

mc

whether to use multicore

verbose

logical, whether to be verbose

progress

logical, whether to be verbose

Value

a cooccurrences-class object

Examples

# NOT RUN {
use("polmineR.sampleCorpus")
merkel <- partition("PLPRBTTXT", text_type = "speech", text_name = ".*Merkel", regex = TRUE)
merkel <- enrich(merkel, pAttribute = "word")
cooc <- cooccurrences(merkel, query = "Deutschland")
# }
