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. Biological data visualization is essential for your research because it validates the hypothesis based on visual inspection of the data analysis. It allows you to compare the gene expression intensities among a large set of samples. The ggplot2 package of R provides various functions to create different graphs and allows modification, annotation, and much more.

BioCode is offering an Introductory R & Data Visualization for Bioinformatics course in which you’ll learn how to write scripts in R language so that you can perform biological data visualizations. You’ll be able 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. In this course, you’ll be able to create publishable figures for research papers, proposals, and review papers.

If you’re a beginner in bioinformatics, an experimental biologist, a bioinformatics researcher, or someone with no knowledge of scripting or bioinformatics, 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 will not only learn how to code in R language but you’ll also be able to perform data visualization with ggplot2 in R on real-world biological data.

This course will include the following section:
