Hi,

The (1 |BLOQUE) is not implemented, yet.

You still need to include a dummy "group", which can contain anything
as far as I remember, but it must be a vector of strings. You can
add a new variable to your dataset:

BLOQUE2$mygroup = rep("a",n)

where n is the number of observations, and use that as your "group".
