conflicting results on NA in a qda predicted object:
Dear list,
(I've not upgraded to R1.4 yet)
I have the following $class component in a predict.qda object:
> unique(mod23S.qda.pred$class)
[1] 12 17 8 10 4 9 5 13 14 19 20 15 6 3 7 1 23 11 18 21 16 2 22 NA

Nevertheless, when I try to identify the individual(s) with NA, I get:
> any(is.na(mod23S.qda.pred$class))
[1] FALSE
and
> mod23...

What is mclust up to? Different clusters found if x and y interchanged
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
