prop.part
counts the number of bipartitions found in a series
of trees given as ...
.
prop.clades
counts the number of times the bipartitions present
in phy
are present in a series of trees given as ...
or
in the list previously computed and given with part
.
boot.phylo
performs a bootstrap analysis.
boot.phylo(phy, x, FUN, B = 100, block = 1)

, (ii) a
series of such objects separated by commas, or (iii) a list
containing such objects.prop.part
; if
this is used then ...
is ignored.prop.part
returns a list with an attribute "number"
. The
elements of this list are the observed clades, and the attribute their
respective numbers. prop.clades
and boot.phylo
returns a numeric vector
which ith element is the number associated to the ith
node of phy
.
FUN
in boot.phylo
must be the function used
to estimate the tree from the original (resampled) data matrix. Thus,
if the tree is estimated with neighbor-joining (see nj
), one
maybe wants something like FUN = function(xx) nj(dist.dna(xx))
. block
in boot.phylo
specifies the number of columns to
be resampled altogether. For instance, if one wants to resample at the
codon-level, then block = 3
must be used.
