I feel comfortable stating that this is the first real version of ppsr. I will be submitting this version to CRAN, hopefully tomorrow.
All scoring and visualization functions now facilitate parallelization, which greatly speeds up the functions on larger datasets.
The negative values of correlations are now highlighted by a more reddish color.
Bugs #11 and #18 related to the classification of non-explicit factors variables were fixed, along with several other bugs.
Unfortunately, I did not manage to get the tests for the parallelized functions working. They did work when tested locally, but not when we were pretending to submit to CRAN using devtools::check(). This is a point that needs looking into.
