Hi

My data  looks like this

 dat=
 X1	X2	Group
84	44	1
86	29	1
94	77	1
78	87	2
94	78	2
60	31	2

I use the formula

form = cbind(X1,X2) ~ Group
poLCA(form,dat)

But i'm getting error stating that 

ALERT: some manifest variables contain values that are not   positive
integers.  For poLCA to run, please recode categorical   outcome variables
to increment from 1 to the maximum number of   outcome categories for each
variable


Please can any one help

              

-----
Thanks in Advance
        Arun
