How to maintain spaces in tip labels?

[Kevin Keegan]

Hello,

I'm trying to annotate a circular tree with tip labels that have spaces between the genus and species name using geom_tiplab2() like so:

 geom_tiplab2(aes(node=node,label=label))

Spaces between the genus and species get removed. For instance Bison bison becomes Bisonbison. Is there a way to preserve spaces?

Perhaps I could use regular expressions to create a string and explicitly add a space between the genus and species names?

Best,

Kevin

the spaces were remove when parsing the tree file.

Any sample file to reproduce this issue?
