Unknown coordinates in highlight and zoom functions.

Question

[Peter.Wood]

I am trying to highlight and zoom specific segments of a OmicCircos plot. In the highlight function their are a number of coordinates which correspond to the region of the circos that will be highlighted.

For example, the highlight function for figure 1 in OmicCircos: A Simple-to-use R Package for the circular Visualization of Multidimentional Omics Data (Ying Hu et al., 2014) is:

highlight <- c(140, 400, 11, 282412.5, 11, 133770314.5, the.col1, the.col1);

From what I understand,

The first number = inner radius,

second number = outer radius

third and fifth numbers = segment name (i.e. chromosome 11),

and the fourth and sixth numbers are coordinates for the graph.

If someone could please describe how you can find these coordinates in R in would be greatly appreciated.
