Which part of functional programming in R do you find hard to understand? Thomas Mailund's book has a lot of focus on R4 but functional programming is so much more. Have you looked at the purrr-packages and the family of apply-functions ? If you want to make your own packages I suggest you read about vctrs: https://vctrs.r-lib.org/ But it sounds like you already have read a lot of materiale including source code so maybe you should not focus on reading. I suggest that you instead just start writing a lot of code yourself. And once every month look at your old code and improve it. Maybe solve some of the many fun problems at https://adventofcode.com/ You can also learn a lot by trying to solve issues with existing packages. Just find the source on github and look at the issues eg. https://github.com/tidyverse/ggplot2/issues Regards Martin ______________________________________________ [email protected] mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide https://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
