I've just added the R programming language to Fedidevs! You can now find 194 programmers on fedidevs!

Thank you @smach for the suggestion! 💙

Another stupid question
RStats or rstats?

The FAQ suggests the latter, but a lot of folk have RStats in their profile

OK, I'm not very experienced with Linux, but having upgraded my old laptop to the latest edition of Mint, I decided to give this a go.

I installed the tidyverse on Ubuntu a long time ago and it took ages

r2u on my new install was light years ahead of my previous experience. < 2 mins to install 100 packages /imports for the tidyverse

data.table and collapse also installed in super fast time.

@eddelbuettel - this is great, and thanks for the clear instructions :)

If you're planning on writing a 📖 here's how many copies you might sell in a year: 70 copies from Amazon (starting june), mostly in USA (God bless USA), and 90 on Leanpub (started selling there in March). Not that bad given the book is available for free online and I'm a nobody!

I was reading a thread about how the norms around blog posts have changed over the years, where “writing something up a blog post” now has a kind of formality to it that it didn’t have 20 years ago (yes, I did in fact have a blog in 2003), which in turn makes blogging feel more like work than joy. This seems like a genuine cultural loss.

So okay. Maybe I can do my part next year. And maybe my last post was a sign that my 2024 blogging resolution should be “I am here to fuck spiders”

@djnavarro

Please never change, I love your blog posts.

I love it when people exhibit some actual personality in their writing.

I'm not sure how well it pans out career wise ( assuming that's the real reason we're all blogging in the rstats world) from my perspective - badly - but at least I can go back and read my posts and enjoy it.

I started out in "educator" mode, but at some point, it all started to feel like too much work. Still does. So now they are glorified notes to self.

Saw a post bemoaning the lack of USB ports on laptops and I'll add lack of ethernet ports to the list.

Attempts to speed up an update by plugging directly to the router have been doomed by lack of said port on the laptop itself..

I don't actually think I could take this pishy wee thing to a meeting and be productive - aside from the lack of ports, the tiny screen renders RStudio / Excel/ SSMS or any other data related tool barely useable.
A desk with monitors and dock is a minimal requirement

peeps: is there any way that allows me to use objects from my rstudio environment to render a quarto doc or do I need to re-run everything from scratch to render a document?

johnmackintosh,
@johnmackintosh@fosstodon.org avatar

@odr_k4tana if you run it as a background job, you get the option to include objects in your global environment

johnmackintosh,
@johnmackintosh@fosstodon.org avatar

@odr_k4tana

You might need to set up a short script to render your quarto file ( for a markdown doc, I'd use the rmarkdown::render() function -there will be a similar function for quarto)

You'll need to ensure your global objects are already in place.

Activate your script, click on Background Jobs tab in RStudio, click on Start Background Job, and it should pick up the correct script. You then have the option to tick the box to run the job with the copy of the global environment.

@odr_k4tana

Perhaps you could also look at {targets}, although, fair warning, it might lead to an unhealthy obsession (been using it solidly for over a year now, fairly life changing as far as R is concerned)

Edit : the beauty of targets is it only runs what it needs to.
So if your source data is updated, it might rerun the entire pipeline.
If only a small portion changes (e.g. you change a function definition) then only objects downstream from that function need updating. All done for you.

johnmackintosh,
@johnmackintosh@fosstodon.org avatar

@odr_k4tana
I have a few introductory posts about it on my blog (you'll find the link on my profile), including a link to a repo where you can try it out on a simple / nonsensical project.

Or just ask questions here, there are quite a few {targets} fans on here now :)

While I dig knowing some base R, I do increasingly find myself using {fs} for anything to do with file manipulation.

The fact that filenames in the console display in different colours according to whether they are directories / files /different file types is a real boon.

It offers fine grained control over the detail you can determine about your files, and if you want to purrrr::walk() over them and modify properties, you can do that too.

Working with files?
For less {ffs}, use {fs}

Looks like I have a slot to talk about {targets} and RAP at the NHS-R conf in October.

On one hand - yay!

On another - oh gawd.

Lessons learned and how to break a large project down into more manageable chunks will definitely be the main thrust, I think.

johnmackintosh,
@johnmackintosh@fosstodon.org avatar

In the unlikely event you were looking forward to this - I've had to withdraw.

Gutted, but too much stuff going in the real / non R world meant I had to do it.

Maybe next year, or maybe I'll just write a blog post and be done with it (but that won't be any time soon).

On the plus side, @brodriguesco is doing what will undoubtedly be a much better / longer / more informative talk about RAP on the same day, so it's a win win all round.

@brodriguesco I managed to see your presentation, it was great! Will be sharing those slides with my colleagues (and the video too, once it hits the NHS-R YouTube)
