alamak's Introduction

Hi there πŸ‘‹

I am a computational biologist - originally trained as molecular biologist - who started learning data analysis in R in 2017. My current areas of expertise include transcriptomics (bulk and single cell), translatomics, neurodevelopmental disorders, neurodegenerative diseases, genome editing, and stem cell biology. I am particularly passionate about data visualization.

Since early 2021 I started honing my skills as a package developer. So fare I have released seven R packages in the wild:

  • 🧠 {coldcuts} - draw and render neuroanatomical segmentations in 2D and 3D
  • 🍳 {oveRlay} - annotate 2D scatterplots with overlay polygons
  • 🎨 {swatcheR} - generate color swatches from pictures
  • 🦜 {alamak} - let Pixel Pals handle your errors
  • πŸ—ΊοΈ {borges} - antique cartographic style 2D point clouds (UMAP, tSNE and the like)
  • 🧫 {cellula} - pipeline with wrappers to many single cell RNA-seq analysis methods
  • 🏒 {HDB} - a geometric test to detect batch effects in single cell RNA-seq

with hopefully more to come.

πŸ›  I am currently learning three.js, a little bit of Python on the side, and Arduino physical computing as a hobby.

alamak's Issues

Use Unicode Block Elements?

  • FYI: You can compress your Pixel Pals by using the Unicode Block Elements: https://en.wikipedia.org/wiki/Block_Elements (use one color for "foreground" color and another for "background" color which can be done via {crayon})

    • You can "losslessly" use "full", "top half", "bottom half", and space to vertically pack "two pixels" within a single character (instead of "one pixel" horizontally spread across two characters)
    • I think "lossy" alogrithms to compress even further using Unicode Block Elements do exist (as used by terminal image viewers) but perhaps out of scope...
  • The R packages {bittermelon} and {bdftools} both do this for compactly rendering bitmap fonts glyphs in the terminal e.g. bittermelon::bm_compress():

Global calling handlers

Funny.

FYI, in R (>= 4.0.0), you can use globalCallingHandlers() to "subscribe" to conditions without having to use withCallingHandlers(). In other words, you can capture and generate your output everywhere.

Gist,

globalCallingHandlers(warning = function(w) {
  message("Woo, careful there: ", conditionMessage(w))
})

and

> as.integer("a")
Woo, careful there: NAs introduced by coercion
[1] NA
Warning message:
NAs introduced by coercion
