Tree Estimation Based on the Minimum Evolution Algorithm

The two FastME functions (balanced and OLS) perform the Minimum Evolution algorithm of Desper and Gascuel (2002).

Keywords
models
Usage
fastme.bal(X, nni = TRUE, spr = TRUE, tbr = TRUE)
  fastme.ols(X, nni = TRUE)
Value

an object of class "phylo".

Examples
### From Saitou and Nei (1987, Table 1):
x <- c(7, 8, 11, 13, 16, 13, 17, 5, 8, 10, 13,
       10, 14, 5, 7, 10, 7, 11, 8, 11, 8, 12,
       5, 6, 10, 9, 13, 8)
M <- matrix(0, 8, 8)
M[lower.tri(M)] <- x
M <- t(M)
M[lower.tri(M)] <- x
dimnames(M) <- list(1:8, 1:8)
tr <- fastme.bal(M)
plot(tr, "u")
### a less theoretical example
data(woodmouse)
trw <- fastme.bal(dist.dna(woodmouse))
plot(trw)
