Welcome!

This book (https://smin95.com/dataviz) guides the reader to be familiar with R, a programming language, for data visualization. It also introduces the R package smplot2, which aims to make the process of data visualization simple. This book was created entirely using RMarkdown for reproducibility.

The old website (on smplot) can be accessed using this link (https://smin95.com/dataviz0).

Reference

Here is the only (and slightly outdated) reference about the package.

Seung Hyun Min, Jiawei Zhou. smplot: An R Package for Easy and Elegant Data Visualization (2021). Frontiers in Genetics, 12:802894. pdf

The codes of the figures in the report are here but these depend on smplot, not smplot2. In near future, I plan to submit smplot2 to CRAN and post its vignette here.

Installation of smplot2

install.packages(c('tidyverse','devtools','gghalves'))

devtools::install_github('smin95/smplot2', force = TRUE)
