[R] Fwd: Overlapping legend in a circular dendrogram

[N Meriam]

Yes I know. Sorry if I reposted this but it's simply because I've
received an email mentioning that the file was too big that's why I
modified my question and reposted it.
I don't want to oblige anyone to respond. I really thought the issue
was my file (too big so nobody received it).

Thanks for your understanding,
Best Myriam
