Planktonic Foraminifera as Oceanographic Proxies: Comparison of Biogeographic Classifications Using Some Southwest Pacific Core-Top Faunas
Figure 3
(a) Agglomerative classification of sites (Figure 1) using presence-absence data with function agnes(). Euclidean metric, Ward cluster strategy. Agglomerative coefficient = 0.83. (b) Agglomerative classification of sites (Figure 1) using ordinal data. Taxa ranked with function daisy(). Sites clustered using five highest ranked taxa using function agnes(). Euclidean metric, Ward cluster strategy. Agglomerative coefficient = 0.86. Functions are in R package cluster available from http://cran.r-project.org/web/packages/cluster/.
