covar_from_df

Transform a data frame to a numeric matrix by one-hot encoding factors.
The last factor value is always omitted to prevent having a singular matrix
when adding a column of 1s (intercept) in models.

Easy-to-use, efficient, flexible and scalable statistical tools.
Package bigstatsr provides and uses Filebacked Big Matrices via memory-mapping.
It provides for instance matrix operations, Principal Component Analysis,
sparse linear supervised models, utility functions and more
