Interface to External Packages

Interface for other packages such as CONSEL (phylogenetic inference), and pvclust (hierarchical clustering)

read.mt(file,tlab="t")

read.ass(file,identity=TRUE,tlab="t",elab="e") 

read.cnt(file)

## S3 method for class 'pvclust'
sbfit(x,...)

sbpvclust(x,mbs,k=3,select="average",...)

Arguments

• file: character of a file name to be read.
• identity: logical. Should the identity association be included?
• tlab: character for basename of tree labels.
• elab: character for basename of edge labels.
• x: an object of class "pvclust".
• mbs: an object of class "scalebootv".
• k: numeric of $k$ for a AU p-value.
• select: character of model name (such as "poly.3") or one of "average" and "best".
• ...: further arguments passed to or from other methods.

Details

CONSEL is a program package consisting of small programs written in the C language for assessing the confidence of phylogenetic tree selection. Some functions for interfacing with CONSEL are: read.mt, read.ass, and read.cnt

for reading, respectively, mt, ass, and cnt

format. Once mt file is read, we can calculate improved versions of approximately unbiased p-values by relltestin scaleboot instead of CONSEL.

pvclust is a R package for hierarchical clustering with p-values. Functions for interface to pvclust are: sbfit method for an object of class "pvclust" to convert it to "scalebootv" class, and sbpvclust for writing back the result to a "pvclust" object with additional class "sbclust". plot method for class "sbclust" overwrites that for "pvclust".

Returns

read.mt returns a matrix of dimension sequence-length by tree-number. If identity=FALSE, then read.ass returns a list containing components x for edge->tree associations and y for tree$\to$edge associations. If identity=TRUE, read.ass returns a list vector of edge$\to$tree associations, where the identity associations for tree$\to$tree are included. read.cnt returns a list containing components bps, nb, and sa to be used for sbfit. The list also contains components cnt, id, and val.

sbfit.pvclust returns an object of class "scalebootv". sbpvclust returns an object of class "sbclust" added to the class "pvclust".

## replace au/bp entries in pvclust object
## see help(lung73) for details
library(pvclust)
data(lung73)
plot(lung73.pvclust) # draw dendrogram of pvlcust object
pvrect(lung73.pvclust)
lung73.new <- sbpvclust(lung73.pvclust,lung73.sb) # au <- k.3
plot(lung73.new) # redraw dendrogram with the new au/bp values
pvrect(lung73.new)
