An update to ggtern, version 1.0.2.0, is now available on CRAN!

This version includes a number of updates, and, additional functionality, which can be summarized below:

• Better Documentation
• Theme commands were brought back inline with the ggplot2 format, for example, theme_tern_bw() has been superceded by theme_bw() as per ggplot2
• The default theme (theme_gray()) was modified to be more alike that of ggplot2 (ie white gridlines, no border)
• Creation of new convenience functions
• Introduction of error handling protocols as per ggplot2, but specific to ggtern
• Use of ‘units’ in ggtern theme elements where appropriate
• Depreciation of element_ternary in favour of individual theme elements.
• Added functionality for secondary ticks, which are ticks on the opposite binary axis to that of the primary ticks.
• Fixes to a number of bugs in the rendering process
