Coe: Coe "super" class

Description

Coe class is the 'parent' or 'super' class of OutCoe, OpnCoe and LdkCoe classes.

Usage

Coe(...)

Arguments

...

anything and, anyway, this function will simply returns a message.

Details

Useful shortcuts are described below. See browseVignettes("Momocs") for a detail of the design behind Momocs' classes. Coe class is the 'parent' class of the following 'child' classes

• OutCoe for coefficients from closed outlines morphometrics
• OpnCoe for coefficients from open outlines morphometrics
• LdkCoe for coefficients from configuration of landmarks morphometrics.

In other words, OutCoe, OpnCoe and LdkCoe classes are all, primarily, Coe objects on which we define generic and specific methods. See their respective help pages for more help. You can access all the methods available for Coe objects with methods(class=Coe).
