 Maintainer: Gorka Navarrete <gorkang@gmail.com>
 Description: Functions to plot and help understand positive and negative predictive values (PPV and NPV), and their relationship with sensitivity, specificity, and prevalence. See Akobeng, A.K. (2007) <doi:10.1111/j.1651-2227.2006.00180.x> for a theoretical overview of the technical concepts and Navarrete et al. (2015) for a practical explanation about the importance of their understanding <doi:10.3389/fpsyg.2015.01327>.

 # README
 
+### v0.3.2 Clean up, test, rinse and repeat
+
+Clean up old comments, add more tests...
+
+* 100% code coverage
+* min_possible_prevalence() is now much more efficient
+* Improvements to overlay = "line" en PPV_heatmap(), now using {ggforce} for labels
+* Changed color palette for NPV
+* Tweaked color palette for PPV
