    Resumi e comentei as recomendações de @zeileis e Murrell sobre quais paletas de cores usar na visualização de cada tipo de dados. O artigo original tem um foco nas melhorias recentes do #RStats, mas meu resumo tem mais a ver com boas práticas em geral

    Hi

    Can anybody point me to good base R plot resources (templates, tutorials …) please?

    No , no …

    Something like and Zeileis & Murrell, "Coloring in R's Blind Spot", The R Journal, 2023 doi.org/10.32614/RJ-2023-071

    Very excited to participate on Haley Jeppson’s panel for “Use of Color in Statistical Charts” at #jsm2023! (Sunday 2-4 PM, CC-810)

    I’ll use this (in progress) collection of @observablehq notebooks for computing on color:

    Thanks to @zeileis, whose colorspace package in R inspired much of this work:

    @lwpembleton I just came across your post. I took it as inspiration to achieve sth similar with base and

    There is one small issue that I could not solve instantly with the Cylinder as a factor. Therefore, this `Cylinders <- as.factor(mtcars$cyl)` hack. Maybe @gmcd or @zeileis has a quick suggestion?

    @rpodcast @rweekly Thanks for the feature and the very kind words about , very much appreciated!

    Quick comment about the "low-tech" format of written/scanned exams: These seem to be becoming more popular again because it's easier to control access to AI tools and prevent cheating etc.

    Alternatively you can export R/exams also to learning management systems like Moodle, Canvas & Co. This also enables embedding individualized data sets for download.
