Working with splines

We will use the ames data set from the modeldata library. It can be loaded using the following code

library(tidymodels)
data("ames")

We will try to predict the Sale_Price of a house by the Longitude of its location (this would not be the best idea alone, but serves as an example). Use step_bs() to fit a spline onto Longitude use cross-validation to find the value of degree where the model performs best.
