[R] problem with da.mix

[Stephanie.Tomczak@eleves.polytech-lille.fr]

Hello,

We use the mix package and we have a problem with the DA function. We aren't
sure, but it's maybbe a memory problem.

We have done:
> Ent<--read.table("C:/.../File.txt")
> attach(Ent)
> Ent 
    V1  V2   V3  V4 ... V16  V17
1    1   1   2   6      18   18 
2    1   1   1   NA     14   17
3    1   1   2   1      16   14
....
199  2   1   NA  7      19   18
200  2   1   3   2      14   17

> EntPrelim<-prelim.mix(as.matrix(Ent),9)
> EntEM<-em.mix(EntPrelim,maxits=500)
> rngseed(1234567)
> EntDA<-da.mix(EntPrelim, EntEM, steps=100, showits=TRUE)
 Steps of data Augmentation:
1... Error in da.mix(EntPrelim, EntEM, steps=100; showits=TRUE):
    Improper posterior--empty cells
