QUESTION
Is it possible to extract, say, a model of class glm
from a tidymodel
built with recipe
and logistic_reg() %>% set_engine("glm")
?
I'd like to use packages from the easystats
project, which require "normal", non-tidy models. The workflow extractor function (pull_workflow_fit()
) returns an object of class `"_glm" "model_fit", which doesn't seem to be compatible.
I understand I can generate a model using glm()
and the same formula as in the recipe
, but it seems to me the fitted parameters differ.
Thanks!

.
QUESTION
I am trying to have code chunks displayed with a dark background in my website generated by pkgdown.
I've been looking for a way to change syntax highlighting in code chunks, but found only little information so far, and nothing that allowed me to tweak or simply change the highlighting theme.
I've tried adding highlight: zenburn
either in the vignette's YAML or in the _pkgdown.yml
but it didn't change anything.
However, I found this code to be put into an extra.css
file in the pkgdown folder to modify certain aspects:

Answered 2019-Apr-22 at 02:26I'm not familiar with the package that you're using, but you should be able to do something like body { background-color: white; }
to change the background color of the entire page.
To change the background color specifically for the code sections, you simply need to change body
above to the relevant selector, so pre, code { background-color: white; }
.
QUESTION
My testing suite is made of multiple files. I would like to skip one of them on travis (the one related to fitting Bayesian models) because it takes to much time and fails.
I know that I can skip specific tests with testthat::skip_on_travis()
. However, these work in a test_that block. Unfortunately, the part I wish to skip (from here to here) is mainly outside the test_that block (and is the model fitting occurring before testing).
I tried putting the model fitting inside a test_that block, but then the other blocks do not find the models. I also tried nested test_that block, but that seems not to work... any ideas?
...ANSWER
Answered 2019-Feb-06 at 16:40In your testthat.R file, you can use the filter
argument to test_check
in order to skip entire files conditionally. This mechanism can be used to skip collections of long tests on CRAN or Travis.
