Databot on NHANES
YouTube video by Data Snacks Databot on NHANES

Trying out #Posit Databot on a dataset I know pretty well (NHANES). I do like how it helps me in my wondering about the data. It's been a while since I've recorded a video, so be gentle. #datascience #R

Why is this piece of code that was fine now throwing an error? Why would it do that on a Friday afternoon? #rstats

Yes, ChatGPT can help you write #rstats code, but so can this old Wiki I created with example code used for common data wrangling needs. Who knows, you might find some gems in there.๐Ÿคทโ€โ™€๏ธ

I make a Data Sources Catalog for every project I work with and I can't tell you how often the project team refers to this document to remember what measures are being collected and when. I highly recommend summarizing your plan in a simple format like this.

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. Itโ€™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:	TODOโ€™s are small, trivial, but necessary changes. Distinguishing todo comments from issues: or suggestions: helps direct the readerโ€™s attention to comments requiring more involvement.
question:	Questions are appropriate if you have a potential concern but are not quite sure if itโ€™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 โ€œofficiallyโ€ 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.

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!

Long overdue shout out for @libbyheeren.bsky.social!

This is an example I've shared. Although it displays as a blank file on OSF until you download it for some reason. :/

What's up everyone! I'm doing a Workshop for Ukraine in #rstats, I finally finished up a flyer. We'll be working on the Lotka-Volterra predator prey model. Just doing some math, coding, and making some nice visualizations. Some thoughts (1/n)

A Friday morning reminder to always review your raw data before you start using it (check variable types, counts, summary stats, etc.) so that you can catch fun things like rows that have been shifted. ๐Ÿ˜‰

I've got a question for the #medlibs...

I'm currently getting a crash course in medical claims data courtesy of Out of Pocket, and in learning about this claims process - the shape of the data via the forms, the rules that need to followed between different code systems - I'm left with the thought
