f_manip_data_2_model_matrix_format: brings data to model.matrix format
In erblast/oetteR: Collection of personal R functions

Description Usage Arguments Value See Also Examples

model.matrix() creates dummy variables for factors. The names of these dummy variables however are not compatible with the formula syntax. This wrapper cleans up the names of the new variables.
