FastME | R Documentation |
The two FastME functions (balanced and OLS) perform the minimum evolution algorithm of Desper and Gascuel (2002).
fastme.bal(X, nni = TRUE, spr = TRUE, tbr = FALSE)
fastme.ols(X, nni = TRUE)
X |
a distance matrix; may be an object of class |
nni |
a logical value; TRUE to perform NNIs (default). |
spr |
ditto for SPRs. |
tbr |
ignored (see details). |
The code to perform topology searches based on TBR (tree bisection and
reconnection) did not run correctly and has been removed after the
release of ape 5.3. A warning is issued if tbr = TRUE
.
an object of class "phylo"
.

### 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)
