Working with ggplot2 in Non-Standard Evaluation Mode: Mastering Flexible and Expressive Plots
Working with ggplot2 in Non-Standard Evaluation Mode Introduction In R programming language, ggplot2 is a popular data visualization library that provides an elegant way to create high-quality plots. One of the key features of ggplot2 is its ability to use non-standard evaluation (NSE) mode. NSE allows users to create expressions involving variable names without having to explicitly reference them. In this article, we will explore how to use aes_string() with non-standard evaluation in ggplot2.
