@m_t_mcnulty Looks like a one and done!

Guess how many takes this took.... 😂

@henrikbengtsson @antoine_fabri @hadleywickham Hadley created this document to compare the forms rpubs.com/hadley/do-call2. It seems the character version is preferred.

@antoine_fabri @hadleywickham , any reason for using do.call("fcn", ...) rather than do.call(fcn, ...) in #do-call" target="_blank" rel="nofollow noopener">adv-r.hadley.nz/quasiquotation…? (read: would you consider switch to do.call(fcn, ...) everywhere?)

For prettier errors and traces call `do.call()` on strings rather than functions. #rstats

@juliasilge Why is a model name required in vetiver_model() when it doesn’t seem to be used when sending to vetiver_api()? Just curious.

@drob Some ideas at these links as well stackoverflow.com/questions/6457… stackoverflow.com/questions/5840…

#rstats question: I often need to pluck out all elements with a particular name wherever they occur in a highly nested structure The below recursive function is the best I've got. Is there something more abstracted?

@StatGarrett When with those caveats, I think it’s pretty neat. Thanks for sharing!

@EmEmEff I just made that diagram to illustrate an idea about teaching. It isn't official documentation about ggplot2 (nor is it particularly complete or up-to-date), but here is the entire diagram if you want it.

@StatGarrett In your materials for training tidyverse instructors (github.com/rstudio-educat…) you used the following image. Do have the full version or can you point to the source? Thanks!

Just realized that the University of Michigan Health System Patient Portal has an easy QR code you can use to add your vaccination status to your iPhone support.apple.com/en-us/HT212752

random #rstats quiz: What does the following line of code return: if(TRUE){1}else{0} + if(TRUE){1}else{0}. Hint: it's not 2. See stackoverflow.com/q/70271938/237…

I've now added a plain-javascript-based GIF encoder to my guide to the GIF file format. Feel free to play around with it to see how LZW compression works matthewflickinger.com/lab/whatsinagi…

I needed an easy way to extract Exif data in #rstats without any system dependencies so I wrote a new package. I seem to enjoy parsing binary files and learning about their structure. github.com/MrFlick/readex…

@psboonstra Just use a funny zoom background and you’ll be fine. Good luck!

Quick #rstats quiz. Are the values of x and y the same or different? stackoverflow.com/q/63432936/237…

@nickseewald It looks like the document is being "optimized" by the hosting provider which is causing trouble. Maybe add data-cfasync="false" to script blocks. Hard to say for sure since I don't have an easy way to replicate your setup to test. See this link support.cloudflare.com/hc/en-us/artic…

@nickseewald Hmm. I see in the developer console that there's a message from "ROCKET LOADER" that the code chunk that's supposed to dynamically load the mathjax library has been detached from the document and thus isn't running. I can't seem to find out why that's happening though.

@nickseewald Can you give a link to an example? Have you checked for errors in the JavaScript console?

@SmightLP OK. Thanks. I did appreciate your YouTube videos on OBS stuff and enjoy your streams very much. Cheers!

@EmEmEff I have an rtmp server, yes. It's rather old now, over 7 years. The OBS forums probably have a better guide than anything I could write.

@SmightLP Do you have a guide to how you include non-local (guest) streams in your OBS stream? Do you have an rtmp server or something? Do you add them as browser source to your scene?

@hfairfield I love to use your 2010 "Driving Shifts Into Reverse" NYT plot when teaching students about good plotting techniques. Have you updated it with more recent data, or can you tell me where to get the data to make an up-to-date version? Thanks!

@ianchillag @alexsnog This was an outstanding episode. Thanks so much!

@colormemoss I’m glad you found the guide useful! I’m disappointed to see that open source project “borrowed” my documentation without proper attribution, but oh well. I hope you had as much fun creating your decoder as I did making mine.

@EmEmEff About a week before you posted this, I was reading that very guide, though at giflib.sourceforge.net/whatsinagif/in…. It was the perfect companion to the spec and really helped me understand the inner workings of the format (I ended up writing a C# decoder). Just wanted to say thanks!

Today I finished writing a pure javascript GIF decoder for my "What's in a GIF" guide to the beloved image file format. I've been meaning to do this for years now. Fun quarantine project. matthewflickinger.com/lab/whatsinagi…
