[R] Error in mkRespMod(fr, family = family) : response must be numeric

[Tania Pollak]

Hi --

I am new to R, and not much more advanced in stats, but am trying to learn
my way through the program to finish my master's thesis.  I am trying to
run tests using glmer, and am getting the above error message.

My code is:

> test1=glmer(V12~V10+(1|V4),family=poisson)
Error in mkRespMod(fr, family = family) : response must be numeric

(The V's are the column numbers for the variable names -- the program
doesn't seem to recognize the actual variable names, although they are in
the table, but does recognize the column numbers.)

Any help is much appreciated.  I tried searching online for some guidance,
but came up empty.

Thank you --

Tania
