(Having taken a quick look at the first few hits I'm not sure this is going to provide a lot of actionable material, but it's worth a look ...)

It would be great if you also ran code like the one above for the first ten or twenty suggestions for the task view maintained by you. After assessing which of the suggestions match the scope of your task view well enough, please update the task view correspondingly. Dylan might also create a GitHub issue for you containing the output from his package so that you can easily have a look and decide which packages to add or not to add.

Start by installing DylanDijk/CTVsuggest and running the shown CTVsuggest(taskview = "MixedModels", n = 5) example, expanding it to the first ten or twenty suggestions. Review whether each suggested package fits the MixedModels task view, then update the task view with the packages that match its scope.
