Bind cross-validation objects

Helper function that combines objects of class cv_ammi, cv_ammif or cv_blup. It is useful when looking for a boxplot containing the RMSPD values of those cross-validation procedures.

Usage

bind_cv(..., bind = "boot", sort = TRUE)

Arguments

...

Input objects of class cv_ammi, cv_ammif or cv_blup.

bind

What data should be used? To plot the RMSPD, use 'boot' (default). Use bind = 'means' to return the RMSPD mean for each model.

sort

Used to sort the RMSPD mean in ascending order.

Value

An object of class cv_ammif. The results will depend on the argument bind. If bind = 'boot' then the RMSPD of all models in ... will be bind to a unique data frame. If bind = 'means' then the RMSPD mean of all models in ... will be bind to an unique data frame.
