doc_topic_matrix: Tidy topic matrices
In MansMeg/tidytopics: Tidy Topic Modeling Toolbox for R

Description Usage Arguments See Also Examples

Calculate a tidy topic document matrix, document topic matrix. These matrices are often very sparse. These can easily be converted to a real sparse matrix using as.sparseMatrix.

doc_topic_matrix(state)

topic_doc_matrix(state)

type_topic_matrix(state)

topic_type_matrix(state)

state

a tidy_topic_state object.

as.sparseMatrix

# Load the state of the union topic model
data("sotu50")
dtm <- doc_topic_matrix(sotu50)
tdm <- topic_doc_matrix(sotu50)
ttm <- type_topic_matrix(sotu50)
ttm <- topic_type_matrix(sotu50)
sp_mat <- as.sparseMatrix(x = ttm)
