Building Stories With Data - Fixing awkward backgrounds in ggplot2
In this article, Cara Thompson shares a solution for fixing awkward backgrounds in ggplot2 when using fixed coordinate systems like coord_sf() or coord_polar(). The issue arises when the background color does not cover the entire export area. She offers several solutions, including one that she finds more elegant, involving the use of the {cowplot} package. By implementing a simple function, one can ensure the background color fills the full plotting area, enhancing the visual consistency of custom-themed graphs and maps within documents.

Building Stories With Data - Optimising the use of colours for storytelling in a spaghetti plot
This article provides guidance on enhancing storytelling in spaghetti plots by optimizing color usage. It discusses data visualization challenges specific to plots with multiple overlapping trend lines, making them difficult to read. Aimed at helping a client who frequently uses these plots, it details strategies to improve clarity and convey stories more effectively. Specifically, the article focuses on altering the 'Orange' dataset in R, including adding fictitious data for illustration. It includes code snippets to modify the dataset, create plots with ggplot2, and improve interpretability by decluttering and selecting harmonious colors, inspired by Piccia Neri's painting.

Calculating and Analyzing Measures of Deprivation in the United States with deprivateR
deprivateR is an R package designed to provide a unified API for calculating and accessing various socioeconomic deprivation indices in the United States, such as the Area Deprivation Index (ADI), Neighborhood Deprivation Index (NDI), and Social Vulnerability Index (SVI), along with the Gini Coefficient. It offers a straightforward interface to compare indices across years and geographies, useful in research and public health. Though valuable, users should note some indices have limited validation for certain Census geographies. The package is available on CRAN and GitHub for easy installation and includes core functions like dep_get_index() and dep_calc_index() for computing deprivation scores using data like the American Community Survey.
