In previous emails, I forgot to mention that maybe I found a (not very important actually) error in your code.

When creating age classes in the dipper example (min 7:46:05 of your video), I understood that you want to create two groups (<1 years old, and  >=1). However, running your code we actually grouped in the same class age==0 && age ==1. It is necessary to add the argument “right = F” to create a group for class <1 [0, 1), and another group for class >=1 [1, 7].
I attached the code with the example. See Ageclass.R.zip

It is also possible that you actually want to group age 0 and 1 in the same group, and then the code is right but I misunderstood the grouping criteria hahaha.
