Visual representation is an important aspect of biological data analysis. This module shows you various visualization tools in R - core library (scatterplot, histogram), venn diagram, heatmap and logoplot. Most time is spent to cover the powerful and versatile ggplot library that allows you to build publication-quality plots.
