Pivoting tidily

This post discusses the new pivot_longer() and pivot_wider() functions from the tidyr package in R. It demonstrates how these functions can facilitate common data processing steps and reduce the need for extensive data wrangling. The post uses an example from a Plant Physiology Lab course to illustrate the use of these functions.

Getting started with Plotly in R

Plotting Age Pyramids with ggplot

Jose M Sallan's blog post titled 'Plotting Age Pyramids with ggplot' outlines the process of creating age pyramids using R and ggplot2. Age pyramids display population distributions by age groups and sex, typically with males on the left and females on the right. The article guides readers through formatting and adjusting data using tidyverse functions, and demonstrates how to plot these pyramids by reading data from a CSV file, cleaning column names, filtering, selecting, and mutating data to reflect proper age groups and percentages. This tutorial caters to those interested in data visualization and demographic analysis.

Porting my favorite RStudio color theme to Positron

This post details the process of adapting the popular Tomorrow Night Bright RStudio theme for use in Positron. The authors discuss their personal journey with the theme, its origins, and how it was ported to other editors.
