In nrauscher/corpus: Toolkit for Corpus Analysis

Description

Get cooccurrence statistics.

Usage

cooccurrences(.Object, ...)

## S4 method for signature 'character'
cooccurrences(.Object, keep = NULL, cpos = NULL,
  pAttribute = "word", window = 5, method = "new", verbose = TRUE)

## S4 method for signature 'partition'
cooccurrences(.Object, window = 5, keep = list(pos =
  c("NN", "ADJA")), method = "ll", big = FALSE, tcm = FALSE, mc = FALSE,
  progress = TRUE, verbose = TRUE, ...)

## S4 method for signature 'partitionBundle'
cooccurrences(.Object,
  mc = getOption("polmineR.mc"), ...)

Arguments

.Object	a partition object
...	further parameters that will be passed into bigmatrix (applies only of big=TRUE)
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
pAttribute	the pAttribute of the tokens
window	no of tokens to the left and to the right of nodes
method	statistical test to use (defaults to "ll")
verbose	logical, whether to be verbose
big	logical, whether to use bigmatrix
tcm	logical, if TRUE, a term-cooccurrence matrix (sparse matrix, simple_triplet_matrix) will be returned
mc	whether to use multicore
progress	logical, whether to be verbose

Value

a cooccurrences-class object

  merkel <- enrich(merkel, pAttribute = "word")
  cooc <- cooccurrences(merkel, keep = NULL)
  cooc <- cooccurrences(merkel, keep = NULL, big = TRUE)
