lda_tidiers (Package: tidytext) : Tidiers for LDA objects from the topicmodels package

Tidy the results of a Latent Dirichlet Allocation.

cast_sparse (Package: tidytext) : Create a sparse matrix from row names, column names, and values

Create a sparse matrix from row names, column names, and values in a table.

● Alias: cast_sparse

pair_count (Package: tidytext) : Count pairs of items that cooccur within a group

This function has been deprecated. Work on this and similar functions is now going on in the widyr package (https://github.com/dgrtwo/widyr). Count the number of times pairs of items cooccur within a group. This returns a table with one row for each word-word pair that occurs within a group, along with n, the number of groups the pair cooccurs in. pair_count_ is the standard-evaluation version that can be programmed with.

unnest_tokens (Package: tidytext) : Split a column into tokens using the tokenizers package

Split a column into tokens using the tokenizers package

● Keywords:
● Alias: unnest_tokens, unnest_tokens_

corpus_tidiers (Package: tidytext) : Tidiers for a corpus object from the quanteda package

Tidy a corpus object from the quanteda package. tidy returns a tbl_df with one-row-per-document, with a text column containing the document's text, and one column for each document-level metadata. glance returns a one-row tbl_df with corpus-level metadata, such as source and created. For Corpus objects from the tm package, see tidy.Corpus.

tdm_tidiers (Package: tidytext) : Tidy DocumentTermMatrix, TermDocumentMatrix, and related objects

Tidy a DocumentTermMatrix or TermDocumentMatrix into a three-column data frame: term{}, and value (with zeros missing), with one-row-per-term-per-document.

● Data Source: CranContrib
● Keywords:
● Alias: tdm_tidiers, tidy.DocumentTermMatrix, tidy.TermDocumentMatrix, tidy.dfmSparse, tidy.simple_triplet_matrix

cast_tdm_ (Package: tidytext) : Casting a data frame to

This turns a "tidy" one-term-per-dopument-per-row data frame into a DocumentTermMatrix or TermDocumentMatrix from the tm package, or a dfm from the quanteda package. Each caster can be called either with non-standard evaluation (bare column names) or character vectors (for cast_tdm_ and cast_dtm_).
