vignettes: Adding extra bars and rectangles
Adding DendSer.R (moving functions into it)
Made sure "rotate_DendSer" shows in the docs.
A new test for `assign_values_to_branches_edgePar` - make sure it deals with Inf and "Inf".
`assign_values_to_branches_edgePar`, `assign_values_to_nodes_nodePar`, `assign_values_to_leaves_nodePar` - now ignores "Inf" also when it is a character by adding as.numeric (and not only if it is numeric!) (this might be a problem if someone would try to update a label with the name "Inf").
Added is.infinite2 and used it so to avoid endless warnings over type coercion...
vignettes: "Enhancing other packages" examples for DendSer, gplots and dynamicTreeCut
Added pvrect2 - a copy of pvrect
update pvrect2 - if we'd ever want one with adjustable lower rects...
New function: `head.dendlist`
vignettes: pvclust, and dendlist sections.
