That is the reason to always state namespace (or how one would call it). For example dplyr::select() and MASS::select(). I prefer to read such code, as I find out what function is from which package (especially if I do not know the package)
#Rstats

this .Rmd supplemental material loads MASS after tidyverse and then uses select(). did they even run it?

The default prior for the intercept in both {rstanarm} and {brms} are very wide.

Counterintuitively - being on the logit scale, this is actually translates to a **strong** prior that p(y=1) is near 1 or near 0.

Always check your priors!

I was aware of {glue} but did not want to add another package to the stack. However, why I am only now finding out about 'str_glue()'? I could have been using it already!

My reviews are generally structured very differently but I might give it a shot.

Andrew Heiss @andrew.heiss.phd · 9d

I recently discovered Conventional Comments (conventionalcomments.org) for providing a pseudo-standard set of labels for feedback and just tried it for an article review and it was really helpful to specify issues vs. thoughts vs. suggestions, etc. Hopefully it's helpful for the authors too!

We strongly suggest using the following labels:

praise: Praises highlight something positive. Try to leave at least one of these comments per review. Do not leave false praise (which can actually be damaging). Do look for something to sincerely praise.
nitpick: Nitpicks are trivial preference-based requests. These should be non-blocking by nature.
suggestion: Suggestions propose improvements to the current subject. It’s important to be explicit and clear on what is being suggested and why it is an improvement. Consider using patches and the blocking or non-blocking decorations to further communicate your intent.
issue: Issues highlight specific problems with the subject under review. These problems can be user-facing or behind the scenes. It is strongly recommended to pair this comment with a suggestion. If you are not sure if a problem exists or not, consider leaving a question.
todo: TODO’s are small, trivial, but necessary changes. Distinguishing todo comments from issues: or suggestions: helps direct the reader’s attention to comments requiring more involvement.
question: Questions are appropriate if you have a potential concern but are not quite sure if it’s relevant or not. Asking the author for clarification or investigation can lead to a quick resolution.
thought: Thoughts represent an idea that popped up from reviewing. These comments are non-blocking by nature, but they are extremely valuable and can lead to more focused initiatives and mentoring opportunities.
chore: Chores are simple tasks that must be done before the subject can be “officially” accepted. Usually, these comments reference some common process. Try to leave a link to the process description so that the reader knows how to resolve the chore.
note: Notes are always non-blocking and simply highlight something the reader should take note of.

This looks cool! As not all co-authors are happy making GH PR, this might be a good solution. Has anyone actually used it?

Like math and plant community ecology?

I am recruiting one or two new Ph.D. students to work on theory and its integration with data in the areas of forest dynamics, species coexistence, or plant community ecology more generally.

On the other hand, the R package {collinear} (URL: blasbenito.github.io/collinear/) saw an increase in downloads after release 2.0, a version with no breaking changes.

Version 3.0 is coming soon, with a few significant improvements and some changes, so we'll see how things go after that.

I find there's a huge mismatch between the standard advice that people give about scientific conference talks, and how people actually give talks.

So I picked out the most important pieces of advice that are most often ignored. 🧪
