Why would you "guess" that? Given your magnitudes, I suspect it's a
scaling issue. Try centering and scaling your Baci variable before
fitting.

From NUM to INT
Ok. I`m trying to run a Poisson glmm with an observation-level random
intercept. But I`m getting the following error for the 'Baci' variable:
'Error: (maxstephalfit) PIRLS step-halvings failed to reduce deviance in
pwrssUpdate'. I guess this message is because the baci variable is not a
an integer, and cannot be transformed into an integer as R has a threshold
of
2x10^9 even in 64 bit R.
It runs fine for the fungii variable.
If you guys want to run the data (attached), the full command is below.
Thanks.

Can you explain why you need them as 'integer', A floating point
representation can hold a value upto ~4.5e15 as an "integer" keeping the
precision that you might need.

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.

From NUM to INT
Dear all:
I converted the columns (Baci, Meti, Fungii, Protozoai) into integers
(using excel) and then imported the data (.txt) into R. Interestingly, the
other three variables were loaded as INT, but the 'Baci' one continued as
Num.
I imported the data using the following command line:
X <- read.delim(file.choose(),
header = TRUE,
dec =
