Function to select colours from a palette by maximizing Mean Perceptual Distance (MPD)
require(picante)
require(colorspace)
#' Select colours from a palette to maximize perceptual distance between the colours
#'
#' This function takes a palette as a character vector of hexidecimal colours, and returns a smaller palette,
#' attempting to maximize the mean perceptual distance (MPD) between the colours in the new palette. It uses CIELAB
#' colorspace to map colour to a perceptually meaningful scale before maximizing distances
#'
#' @param pal A palette as a character vector containing hexidecimal coded colours
#' @param sat.thresh Minimum saturation of colours in resulting palette (between 0 and 1)

Is there an easy way to convert a named list into a dataframe, preserving the elements of the list in a "list-column"?

library(dplyr)
library(magrittr)

## make a random matrix
rand_mat <- function() {
  Nrow <- sample(2:15,1)

Ncol <- sample(2:15,1)

Modern R Development Guide

This document captures current best practices for R development, emphasizing modern tidyverse patterns, performance, and style. Last updated: August 2025

Core Principles

  1. Use modern tidyverse patterns - Prioritize dplyr 1.1+ features, native pipe, and current APIs
  2. Profile before optimizing - Use profvis and bench to identify real bottlenecks
  3. Write readable code first - Optimize only when necessary and after profiling
  4. Follow tidyverse style guide - Consistent naming, spacing, and structure
