Details

Version numbers have the format .., like 0.9.2. This function compares the current version number of ggplot2 against the specified version, which is the most recent version before the function (or other object) was deprecated.

tern_dep will give an error, warning, or message, depending on the difference between the current ggtern version and the specified version.

If the current major number is greater than version's major number, or if the current minor number is more than 1 greater than version's minor number, give an error.

If the current minor number differs from version's minor number by one, give a warning.

If the current subminor number differs from version's subminor number, print a message.
