text2map: R Tools for Text Matrices
This is an R Package with libraries and utility functions for computational text analysis.
The functions are optimized for working with various kinds of text matrices. Focusing on the text matrix as the primary object – which is represented either as a base
R dense matrix or a
Matrix package sparse matrix – allows for a consistent and intuitive interface that stays close to the underlying mathematical foundation of computational text analysis. In particular, the package includes functions for working with word embeddings, text networks, and document-term matrices.

We welcome contributions!
For any contributions, feel free to fork the package repository on GitLab or submit pull requests. We follow the Tidyverse and rOpensci style guides (see also Advanced R). In terms of adding functions, we encourage any method that works with base R matrices or the Matrix package’s
