Example doesn't work - no applicable method for 'explain' applied to an object of class "htest"

[SchmidtPaul]

I just tried to run the example

devtools::install_github("hilaryparker/explainr")
library(explainr)
ptest <- prop.test(x = 500, n = 1008)
explain(ptest)

and got the following message

no applicable method for 'explain' applied to an object of class "htest"

Am I missing something here or did maybe the class of objects from prop.test() change recently?

I ran it with stats package 3.6.2 and it worked. Then again with version 4.0.0 and I got the same error.
When I run class(ptest) in both environments they bot return "htest"

I think it has something to do with missing @export tags / NAMESPACE? Even though sloop::s3_dispatch(ptest) does show that it's dispatching on the explain.default method.

I don't know enough about the magic to understand why, but I got it to work by:

• downloading the source
• deleting NAMESPACE
• adding @export to explain.default documentation
• devtools::document()
• devtools::load_all()
