Code Broken Ch 10

[biscotty666]

In 10.1, estimate_perf(lm_fit, ames_train) fails with

! Can't subset columns that don't exist.
✖ Columns `Gr_Liv_Area`, `Bldg_Type_TwoFmCon`, `Bldg_Type_Duplex`, `Bldg_Type_Twnhs`, and `Bldg_Type_TwnhsE` don't exist.

Running the code in 8.8 solves the problem.

Thank you for the wonderful book.

It doesn't fail per se, because as stated previously to the example:

"Let’s again use the Ames housing data to demonstrate these concepts. Section 8.8 summarizes the current state of our Ames analysis."

It is using the data resulting from Section 8.8.

And when rendering the chapter, it's ensure that this data will be available when calling in the source code:

source("ames_snippets.R")
load("RData/lm_fit.RData")

It was just an fyi. I ran the code with the snippets and data file from the repo, indeed with a full clone of the repo. It's not a problem for me but I just thought you might want to know the code in the repo didn't run cleanly. Indeed, for someone just reading and following the book and the instructions it doesn't matter.​ Cheers

Thanks, @biscotty666 and @davidrsch! We don't consider this broken code but in fact as designed. Throughout the book, there are summaries at the end of the chapters of where we are in the analysis and then we refer to them in later chapters, like @davidrsch pointed out. There would be too much repeated code otherwise for the reader, in our option.

Thanks again!
