NEW FEATURES
+ o There three new methods for the "multiPhylo" class: str, $,
+ and [[.
+
o root() gains the options 'node' and 'resolve.root'
(FALSE by default) as well as its code being improved.
o mltt.plot() has now an option 'log' used in the same way
- than in plot.default()
+ than in plot.default().
BUG FIXES
'cex' to draw symbols of different sizes (which has
worked already for thermometers).
+ o read.nexus() generally failed to read very big files.
+
OTHER CHANGES
o The argument 'family' of compar.gee() can now be a function
as well as a character string.
+ o read.tree() and read.nexus() now return an unnamed list if
+ 'tree.names = NULL'.
+
+ o read.nexus() now returns a modified object of class "multiPhylo"
+ when there is a TRANSLATE block in the NEXUS file: the individual
+ trees have no 'tip.label' vector, but the list has a 'TipLabel'
+ attribute. The new methods '$' and '[[' set these elements
+ correctly when extracting trees.
