[bug#45565] [PATCH 0/2] Add more r-mlr3 add-ons

[Wiktor Żelazny]

A false alarm yesterday regarding the r-mlr3pipelines determinism. I
confused the derivation hash with the build hash. As for r-mlr3ordinal,
the linter reported

./gnu/packages/cran.scm:25616:15: r-mlr3ordinal@0.1.0-9000-0.9febac9: the source file name should contain the package name

I don’t know what “source file name” is referenced here, so I’m
submitting the definition as it is.

bug#45565: [PATCH 0/2] Add more r-mlr3 add-ons

[Ricardo Wurmus]

Hi Wiktor,

I’m terribly sorry for the delay.  These two patches are fine and
slipped through the cracks.  I updated the packages to the new input
style and pushed them to the “master” branch.

This is due to the use of git-reference; you need to provide “file-name”
to give a name to the source checkout.  I did this when I applied your
patches.

Thanks for these patches!
