Hi R-Helpers:
 I?m trying to use the function GLMM from lme4 package, (R-1.8.1, Windows
98),and I get the following error:
+                   fert+
+                   remo+
+                   sitio:fert+
+                   remo:sitio+
+                   remo:fert+
+                   remo:fert:sitio
+             data=datos,
+             family=binomial,
+             random=~repe:sitio)
Error in parse(file, n, text, prompt) : parse error
wrong.
 Also in GLMM?s help page say that data is an "optional" data frame used as
the first place to find variables in the formulae, but if I omit data=datos
(previously I have done attach(datos)), the error change to:
+                    fert+
+                    remo+
+                    sitio:fert+
+                    remo:sitio+
+                    remo:fert+
+                    remo:fert:sitio,
+                    family=binomial,
+                    random=~repe:sitio)
Error in model.frame.default(formula = formula, data = data,
drop.unused.levels = TRUE) :
        Argument "data" is missing, with no default

This is not what I was expecting for "an optional data frame",
Thanks in advance for any help.
Gabriela.

Could you tell us the version of the lme4 package please?
Well if you are going to be picky about it! :-)

I guess the optional data frame is not quite as optional as we had
intended.  Time to add another check.  Thanks for pointing this out.
