I could never unlearn base R to know how it feels like to do ds stuff with tidyverse only. But I've mentored (tutored) people that did it all with tidyverse, and that took courses 100% taught with tidyverse. I think the biggest proof that sth works is: are ppl acheiving what they want with it?

But, of course, anyone can learn anything! And tidyverse makes data science in R much easier.

Base R and tidyverse are not excludent, they are complementary.

I just thought that, since I started learning R from ta book that was fully in base R, even the plots, this basic understanding I had helped me get pandas easier than I believe would be for newer R learners that did not need to know base R.

OMG the proportion this post took. This is NOT a hateful post for tidyverse. I love tidyverse!
It is only a person pov while doing more stuff with python pandas*. As @nrennie.bsky.social pointed out, polars is more similar to the tidyverse.

It is much easier to understand python code for data science if you know a bit of base R than if you only know tidyverse.

Using quarto with python is a whole new experience. It is *not* a simple switch of languages (if you're an R user like me).

I use Google Slides. It is much easier to organize the disposition of figures and text boxes than by using quarto. In quarto, I would need to google (or ask an LLM) how to move a figure, or adjust the layout by writing everything. Dragging and droping, and seeing it right away is simpler.

We also have a separate programme for the Global South. If your idea is selected, we will bring the event to your region.

Wow.

Thanks for the explanation! Very interesting, indeed. Will check it out in my next trip to the US!

Is there any buzzfeed-like quiz out there yet to figure out which AI model is the best for you?
It would be fun.

How come, a mushroom coffee? Does it taste more like coffee or more like mushrooms?

I am a coffee lover, wouldn't trade it for anything, but I am very curious about this exquisite drink you posted about!

{ellmer} 10/10 in stability to extract structured from unstructured data using #gemini API.

I used type_object() to set the desired output, and json to set the input. I'm still experimenting with LLM API calls, but so far it was much better error-wise than a python script with schemas.

Guys, you need to come up with a better strategy of getting rid of robots. I lose half of my day recognizing buses, bikes and stairs.

Creating a package to organize my work, instead of just reloading functions from scripts, was the best thing I did so far this year.

If you'd like your files to be ordered by "last modified" in the explorer, you can append the following config to your settings.json:

{
"explorer.sortOrder": "modified"
}

Works both in #positron and in #vscode.

If you are using independent training and testing sets which need PCA calculation in genomics, be sure to do it using projection and to the same panel, alongside the same parameters (maf, ld and missingness). Otherwise, you are comparing bananas to apples.

3 things I learned from @stephenturner.us workshop on #R pkg development in #Positron

- there is a light bulb icon that creates a roxygen template for an R file

- available::available("pkgname") checks if the name you want has already been used

- {pkgndep} evaluates heaviness of pkg dependencies

I use a gist everytime I need to run a few basic #bioinformatics explorations in a new instance, and thought I could share it here so someone could benefit from it too!

I have forked it and adapted a bit to my needs. Here it goes:

poisonfrogs: Color Palettes Inspired by Neotropical Poison Frogs laurenoconnelllab.github.io/poisonfrogs/ #Rstats

Really nice work by @nbaya.bsky.social and co. showing that, as expected, individuals whose observed phenotype deviates from their genetically predicted trait are enriched for rare damaging variants in associated genes with said trait.

Now to see if embryo selection companies pick up on this 😉

Crazy interesting biology!
I wonder if there is any phenotypic evidence of this chimerism.
