Phylogenetic algorithm selection

See http://pga.lbl.gov/Workshop/April2002/lectures/Olken.pdf for details, in brief:

• Continuous characters, lots of data, few computing resources ==> Neighbor joining
• Discrete characters, few mutations / homoplasy ==> Maximum Parsimony
• Discrete characters, limited sequence lengths, some homoplasy ==> Maximum Likelihood Estimation
• Discrete characters, many taxa ==> Supertree
• Complete genomes ==> Whole genome phylogeny

Statistics R command

. Read a file
height <- read.table("H:/public folder/hzhang/R/height.txt",header=T) . Print summary summary(height) . Set the factor level height$Treatment <- relevel(height$Treatment, ref="kitaake") . Variance analysis summary(lm((height$Height~height$Treatment)))
