which controls the outermost loop

(thanks to Emmanuel and Liat)
CHANGES in PHANGORN VERSION 1.0-1

(parsimony and likelihood based)

o subset functions for phyDat objects
BUG FIXES
o an error in pace is fixed
OTHER CHANGES
o parsimony (fitch and sankoff) can now handle multiPhylo objects

matrix
CHANGES IN PHANGORN VERSION 0.99-6
NEW FEATURES
o pace, extracts the ancestral states of the root of a tree
using the sankoff algorithm
BUG FIXES
o fixed a bug in dist.ml (thanks to Emmanuel)
o fixed a bug introduced to SH.test in 0.99-5
OTHER CHANGES
o fixed several spelling mistakes in the documentation
CHANGES IN PHANGORN VERSION 0.99-5
NEW FEATURES
o parallel computing via multicore
(so far bootstrap.pml, bootstrap.pml profit under linux)
o compute edge weights for parsimony trees
BUG FIXES
o optim.pml had problems when
o as.character converted ?,- wrongly to NA
o fitch needed binary trees as input, otherwise pscore is
likely to be wrong (returns now a warning)
o optim.pml had a problem with identical sequences
OTHER CHANGES
o optim.parsimony returns now a tree with edge weights
o vignette is enhanced, I fixed some spelling mistakes and added
some more examples.
CHANGES IN PHANGORN VERSION 0.99-4
NEW FEATURES
o new generic function unique.phyDat
OTHER CHANGES
o internal data format phyDat changed
and data are stored more memory efficient
(optim.pml and friends use less memory and may be faster)
CHANGES IN PHANGORN VERSION 0.99-3
BUG FIXES
o RF.dist sometimes returned wrong distances
o rate parameter is now properly normalized in pml.Part
and pmlCluster
o simSeq had problems simulating a single character
NEW FEATURES
o rSPR and rNNI to simulate tree rearrangements
CHANGES IN PHANGORN VERSION 0.99-2
NEW FEATURES
o bootstrap.pml and bootstrap.phyDat: parametric
bootstrap methods
o simSeq: A new function to simulate sequence data
o read.phyDat: simplifies reading in alignments
o SH.test: Shimodaira-Hasegawa test
o RF.dist: Robinson-Foulds distance as replacement
for treedist (uses less memory and is much faster)
BUG FIXES
o dist.ml returned wrong variances.
o as.character.phyDat, as.data.frame caused an error
for alignments with only one site.
OTHER CHANGES
o added vignette describing how to perform some
standard phylogenetic analysis with phangorn.
o more functions to convert between different data formats.
o NNI tree search is now general possible for
partition models (pmlPart, pmlCluster)

o pmlPen: A new function to estimate penalized likelihood models
for sets of edge weights in mixtures or partition models.
BUG FIXES
o dist.ml should be more forgiving for different inputs.
OTHER CHANGES
o a new dataset.
CHANGES IN PHANGORN VERSION 0.0-3
NEW FEATURES
o amino acid models
o several new maximum likelihood models:
mixture models (pmlMix), and some model for
phylogenomic data partition models (pmlPart),
and clustering of partitions / genes (pmlCluster)
(still experimental, feed back wellcome)
o design matrices for phylogenetic distance methods
o added some functions useful for simulations
(nni, allTrees)
