[R] clustering

[WeiWei Shi]

Hi,
I just get a question (sorry if it is a dumb one) and I "phase" my
question in the following R codes:

group1<-rnorm(n=50, mean=0, sd=1)
group2<-rnorm(n=20, mean=1, sd=1.5)
group3<-c(group1,group2)


Now, if I am given a dataset from group3, what method (discriminant
analysis, clustering, maybe) is the best to cluster them by using R.
The known info includes: 2 clusters, normal distribution (but the
parameters are unknown).

Thanks,

Ed
