An updated version of qwraps with a focus on flexibility and general purpose. These functions are helpful for extracting and formatting results from R into .Rnw or .Rmd files. Additional functions for routine work such as extracting results from regression models or finding sensitivity and specificity.

    "Pos. (\\%)" = ~ qwraps2::n_perc(pos == "pos."))

                           qable_args = list()

new_table
