[R] is.numeric () FALSE

[Alannah]

Jeff,
The dataset are 3D landmarks taken from a skull (Homo being the dataset of 3
species of the genus Homo) I am trying to perform Generalised Procrustes
Distance and superimposition and as you can see,  I am told x is not True.
If I also perform is.numeric(Homo) I am told that it is FALSE. I hope that
is enough context for you. I also hope you know what's going wrong in my
dataset.
