A whole genome analysis of multiple data series is often presented in a circular manner with concentric circles, each showing different kinds of data with a different representation in each. These plots, called Circos plots, are extremely powerful and can show a lot of dense information in a compact form. In this recipe, we'll look at constructing such plots in R from common genomics data files.
Constructing circular genome plots of polyomic data
Getting ready
To make Circos plots, we'll use the circlize package and the four files prefixed with arabidopsis in the datasets/ch7/ folder of this book's repository.
