get_root_branches_attr.Rdget attributes from the dendrogram's root(!) branches
get_root_branches_attr(dend, the_attr, warn = dendextend_options("warn"), ...)dendrogram object
the attribute to get from the branches (for example "height")
logical (default from dendextend_options("warn") is FALSE). Set if warning are to be issued, it is safer to keep this at TRUE, but for keeping the noise down, the default is FALSE. Should a warning be printed when the function is used on an object which is NOT a dendrogram.
