[R] Mixture of 1-dimensional Normals

[Christian Hennig]

Dear list,

I tried to fit a mixture of 2 normals using library mclust:

> x <- c(rnorm(50),rnorm(50,mean=1000))
> mx <- as.matrix(x)
> emx <- emclust(mx,nclus=2,modelid="EEE")
Error in emclust(mx, nclus = 2, modelid = "EEE") : 
	data must be matrix-conformal

(Other modelid: Same problem.)

Does this mean that emclust does not work on 1-dimensional data?
If so, how to fit a mixture of 1-dimensional normals?

Best,
Christian
