Error in pkg(tidymodels)

[fdepaolis]

When running bookdown::render_book("index.Rmd", "bookdown::gitbook")

I get the following:

processing file: _main.Rmd |............. | 14% inline R code fragments

Quitting from lines 2-43 (_main.Rmd) Error in pkg(tidymodels) : could not find function "pkg"

And I couldn't find any support on pkg() anywhere. Thank you

If you are wanting to render the book yourself, you should be aware that it takes a very, very long time (it takes 4+ hours on GitHub actions).

The pkg() function is in _common.R:

https://github.com/tidymodels/TMwR/blob/ce2b4fc2177e385c7fd29ecf0ebce0219e050ce2/_common.R#L39-L43

Which we tell bookdown to use here:

https://github.com/tidymodels/TMwR/blob/ce2b4fc2177e385c7fd29ecf0ebce0219e050ce2/_bookdown.yml#L35

I expect that you have maybe changed or are not using one of these?

Thank you for your detailed explanation. No, I wasn't planning on actually building the html files...but thank you for the warning about the time it takes. For some reason, the pkg function wasn't loaded. I'm not sure there is something missing or if others have encountered the same issue when running the instructions in "Readme.md." There is no mention of having to run the ".R" scripts. Also, I was curious because the title is "Reproducing the book or results" and I was more interested in the results. I seemed to me that it was easier just to read the book from the website (https://www.tmwr.org). In any case, thank you very much.

You don't have to run those scripts manually; they get picked up automatically by bookdown if the yaml file is in the right spot. You can see how GH Actions builds the book here:

https://github.com/tidymodels/TMwR/blob/ce2b4fc2177e385c7fd29ecf0ebce0219e050ce2/.github/workflows/bookdown.yaml#L37

It's definitely easier to read the book as rendered online! Let us know if you have further questions.
