Dear R users, I am happy to announce that the package fastDummies is now on CRAN (*https://cran.r-project.org/package=fastDummies <https://cran.r-project.org/package=fastDummies>)*. The fastDummies package lets you quickly and easily create dummy columns from categorical variables in data.tables or data.frames. This package is much faster than model.matrix() in handling data with greater than 1,000 rows. Please submit all question or issues here (https://github.com/jacobkap/ fastDummies/issues) Best, Jacob [[alternative HTML version deleted]]
