I'm trying to follow one of Julia Silge's Tidymodel tutorials on Youtube as I attempt to brush up on my ML experience. In this tutorial she demonstrates 2 or 3 different approaches for dimensionality reduction.
Julia uses a billboard dataset and tries to predict the number of weeks in the charts whereas I am using the Ames housing dataset and trying to predict Sale_Price.
Where I am coming unstuck is at 23:51 when she preps a recipe and tidies the result. In her tidied result she has a column called component which I am missing which is preventing me from moving to the next step.
I am stuck at line 104-108 in my file as I don't have a component field, could anyone enlighten me please?
My file is available here on github.
