Looks like I may have to write my own crappy data-frame-to-PDF exporter. I just want something quick-and-dirty. Not having to import the entire latex/rmarkdown ecosystem. #rstats

@coolbutuseless huxtable is the only one I know of with a write-to-pdf function. https://hughjonesd.github.io/huxtable/reference/quick-output.html

#rstats Hive Mind: What's the latest/greatest tables package for R? I'm looking for something that (somehow!) does direct pdf/png output. So in my script I have: write_pdf_table(mtcars, ...) Or do I still have to build markdown template documents first or something?

Hey, #hpc folks. Is there a tool for parsing PBS directives from a bash script? Specifically I want to extract specifically the walltime, ncpus and mem requested. I would like to avoid reading the text and parsing it myself because... well, I hardly need to finish that sentence.

@coolbutuseless It’s so sad…

🚨 #rstats folks- I learned this the hard way and I'm hoping to spare you frustration: I thought my file loaded correctly because I DID get some data, not realizing that some rows were missing! If nrow(your_data) ≠ R.utils::countLines("file_you_got_your_data_from.csv"), here's how to fix it:

Two crazy dudes that did: ✅ R Dev Day at #RSEcon2025 ✅ tidyverse Dev Day at #positconf2025 a week later My patches and PRs need more work but @shikokuchuo.net got so much done 💪

#rstats Dev Diary - Ray marching through a signed distance field (a sphere intersected with 2 cylinders) I now have some ambient occlusion calculations working. Shading indicates the ambient occlusion factor which will be used to modify the global lighting on the object.

#rstats tidy dev day 2025 in the books! I managed to ring the gong five times by making the following PRs:

I hate hamburger menus, but couldn't get around having one in my game. Made myself feel better by assembling the hamburger out of UTF-8 † entities. (The font is Avona Serif.) #gamedev

#rstats Dev Diary - figured out a scaling issue with SDFs. Can now render the canonical SDF object with ray marching. It''s base R, so not super fast. Still 1-ray-per-pixel, orthogonal projection. 1. Shading by Z-coordinate 2. Shading by number of ray-marching steps to hit surface

#rstats Hivemind: Latest #rstudio has defaulted to saving R files with a lowercase ".r" extension. How do I get it to revert to uppercase ".R" extension?

#rstats Dev Diary - ray marching a signed distance field (SDF) - minimal viable code * 1 ray per pixel * orthogonal projection * object z-coord mapped to intensity

#rstats Dev Diary - I think I'm going to end up writing a dogy sphere-tracer for rendering signed distance fields. Materializing SDF data to polygons (or even voxel coordinates) requires evalation throughout an n^3 volume. But for simply viewing it can be much simpler (n^2 * log(n) maybe??) […]

#rstats Dev Diary - 3d rendering for art's sake Infinite repeating lumpy spheres with half-arsed perspective correction rendered using "grid.polygon()"

#rstats Dev Diary - Experimenting with animated abstract 3d rendering. This is a dancing space-filling curve (gyroid). Renrdered via: Signed-distance field, Marching-cubes + {grid} render

#rstats Dev Diary - rendering polygon meshes using {grid} graphics * keep only triangles facing camera * Shade by dot(normal, light direction). * Draw "grid.polygon()" from back to front * No perspective correction (yet?) Not fast, but it beats firing up {rgl} for quick visualization

@coolbutuseless apparenly you hate S4 so much it doesn't even get a mention. :-)

#rstats Dev Diary: #csg A signed distance field representing a knot is rendered in isocubes and as a polygon mesh

“Unlike a typical mesh, which stores per-vertex 3D positions, a mescher stores per-vertex 2D screen-space positions and a per-edge depth difference. Whereas differences in depth across edges must sum up to zero as we travel around a standard mesh, this is not […] [Original post on mathstodon.xyz]

PS. @mathsgear Do you have any idea how much puzzle enthusiasts are willing to pay for nicely-made niche puzzles? You should consider doubling the price, at least. But wait till my friends have had a chance to buy it cheaply first. :-)

@coolbutuseless It's an utter mystery every time.
