#Load data and create the base plot.
plot <- ggtern() + theme_bw() + 
 theme(tern.axis.ticks.length.major=unit(3.0,'mm'),

plot

#Show Arrows
last_plot() + theme_showarrows()

last_plot() + theme_showgrid()

#Clockwise/Anticlockwise Precession

#Show/Hide BOTH Primary and Secondary Ticks

last_plot() + theme_hideticks()

#Show/Hide EITHER Primary OR Secondary Ticks.
