Biological data visualization is an important aspect of bioinformatics which involves the graphical representation of unstructured or structured data to display information hidden in the plots/graphs. The ggplot2 package of R provides various functions to create different graphs and allows modification, annotation, and much more. Learning biological data visualization can not only help you in creating beautiful data visualization but also in making impactful decisions during your research based on data visualizations along with publishable figures for your research papers.

BioCode is offering an advanced biological data visualization with ggplot2 & R course in which you’ll learn how to write customized scripts to generate publication-ready and high-quality graphical plots of biological datasets to visualize, analyze and compare the datasets in a more insightful way, such as volcano plots, heatmap, dot plots, frequency plots, scatter plots, histograms, and bar charts with customized labeling. Even if you don’t know programming or R language at all, in this workshop you’ll learn R language from the basics to the advanced level and then apply your script-writing skills to data visualizations.

Whether you’re a beginner in bioinformatics, an experimental biologist, or a bioinformatics researcher, our course will help you greatly. You’ll be practicing on a case study of human mitochondrial proteome and genome along with a real-world gene expression dataset. Therefore, you’ll not only learn data visualization with ggplot2 in R, but you’ll also do real-world biological data visualization in this biological data visualization with ggplot2 in R workshop.

This course will include the following section:

Section 1: Data Visualization Using ggplot2

Description: This section will focus on making sure that the students learn how biological data is visualized using the ggplot2 package in R language.
