Hello All... I gave a task to my students that involved using mclust to look for clusters in some bivariate data of isotopes vs various mining locations. They discovered something I didn?t expect; the data (called tur) is appended below. p <- qplot(x = dD, y = dCu65, data = tur, color = mine) print(p) # simple bivariate plot of the data; looks fine mod1 <- Mclust(tur[,2:3]) mod1$G mod2 <- Mclust(tur[,3:2]) mod2$G One can use coordProj to see the clusters found, but the basic result is that mclust found 3 clusters in mod1, but if you interchange the x a...
