Usage

as_cooccurrence(x)

Arguments

`x`	a matrix or sparseMatrix

Value

a data.frame with columns term1, term2 and cooc where the data in cooc contain the content of the cells in the matrix for the combination of term1 and term2

Examples

data(brussels_reviews_anno)
x <- subset(brussels_reviews_anno, language == "nl")
dtm <- document_term_frequencies(x = x, document = "doc_id", term = "token")
dtm <- document_term_matrix(dtm)

correlation <- dtm_cor(dtm)
cooc <- as_cooccurrence(correlation)
head(cooc)
