Release 0.3.1 (hotfix) published on Github 25 April 2018
Changed version # to 3.1
Added percent scales to percent plot using the scales package which necessitated changes in DESCRIPTION and NAMESPACE
Added some code to keep track of missing values that are omitted in calculations and plotting
Creating the ggtitle with a bquote seemed to be creating issues with both performance and also creating intermittent errors if the title was long. Replaced bquote with sprintf and while I was at it changed how it presents
Rebuilt vignettes and doco as needed to show the changes
