[R] pb with package mix

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

hello,

We've got a problem with the mix package in order to impute the missing data.
After importing the data, the prelim function does not work (only the stlouis
data works).

We have done :

>library(mix)
>Manq <- read.table("C:/.../file.txt")
>attach(Manq)
>save(Manq,file="C:/../R/rw2001/library/mix/data/Manq.rda")
>data(Manq)
>Manq
 V1 V2 V3 V4
1  1  1  1  1
2  1  1  3  6
3  1  2  6  2
...
...
52  2  7  6  2

>Essaimanq <-prelim.mix(Manq,4)
  Error in as.integer.default(list(V1 = c(1, 1,  1,  1,  1,  1, 1,  1,  1,  1,:
     (list) object cannot be coerced to integer   

thank you
