(Remotely Taught Module) - Data Visualization in R

We are offering a new remotely taught module on data visualization in R. You will learn some of the most essential tools needed for exploratory data analysis. Especially, if you heard about the powerful ggplot library, but its logic appears complicated, this module is perfect for you.

Visualization is an important component of bioinformatic analysis. We plot our data in different ways to discover patterns and then further explore those patterns for their statistical validity. Examples of this approach include fitting straight line through related numbers, building phylogeny tree to find evolutionarily-related genes and creating heatmaps of RNAseq data.

R is an excellent tool for visual analysis for two reasons - (i) vector-based representation of data, (ii) powerful libraries like ggplot. If you use R but are not comfortable with its visualization libraries, this module is right for you.
