Details

In ggtern, the primary ticks are deemed as being the ticks along the binary axis increasing to the apex species, primary ticks can consist of both major and minor ticks (major ticks have labels, and are generally longer and bolder). Therefore, there are three (3) sets of major primary ticks, and, three (3) sets of minor primary ticks.

These convenience functions introduce the concept of secondary ticks, which, are the same items however on the 'opposing' binary axis.

For example, considering the TOP apex species, in a plot with 'clockwise' axis precession, the primary ticks would run along the LHS, whilst, the secondary ticks, woudl run along the RHS. By default, the primary ticks are switched ON, whilst the secondary ticks are switched OFF and are controlled by the tern.axis.ticks.primary.show and tern.axis.ticks.secondary.show theme elements respectively.

theme_showsecondary is a function that apends to the current theme a flag to switch ON the secondary ticks theme_showticks(), themehideticks(), theme_noticks() are functions that switch ON or OFF BOTH the primary or secondary ticks. theme_nosecondary or theme_hidesecondary (Alias) are functions that apends to the current theme a flag to switch OFF the secondary ticks theme_showprimary is a function that apends to the current theme a flag to switch ON the primary ticks theme_noprimary or theme_hideprimary (Alias) are functions that apends to the current theme a flag to switch OFF the primary ticks
