Add a title to the graph generated using the R circlize package

Question

How can I added a title to the circos plot generated using the circlize package, please? I didn't find any reference in the manual.

Answer 1

No, title is not mentioned in the manual. On the other hand, if you study the excellent circlize vignette (it's actually a book of 171 pages!), you find that:

circlize is built on the base R graphic system, then, of course the base graphic functions can be used in combination with circlize functions. [...]

Normally, the base functions such as title(), text(), legend() can be used to add extra information on the plot

Thus, just add title() after your circlize plot call.
