Dice dissimilarity output and 'phylo' function in R
...compared the
distances computed in R with that from NTSYS or SAS,
for example dice and jaccard coefficients I realised
that the dice distances are very different while the
jaccard distances are the same with those from these
other softwares.
The codes I used for a small example are shown below:
samptest4<- scan (file = "samp-test4.txt")
samptest4<- matrix(data = samptest4,nrow=8, ncol=4,
byrow=T)
library(MASS)
library(arules)
library(ape)
#CFI<- numeric (M)
CFI <- function(ctree)
{
(ctree$Nnode -1)/(length(ctree$tip.label) - 2)
}
#calculation of dissimilarities & co...
