[R-sig-ME] How to generate the equation of a GLMM?

[Marina Pastor]

Dear all,
I have to obtain the equation of a GLMM. I hoped to do it using the  
equatiomatic package, but it does not generate the equations for GLMM.  
Any other package to generate it?
I have two different GLMMs:
- For the first one (glmer.nb(Zooplankton ~ offset(filtered volume) +  
Temp + Sal + (1|stationNumber), data)) I think I managed to generate  
the equation manually (the coefficients are below), but what I should  
add as offset?
The equation: Y = 20.57 + 1.17 Temp -2.12 Sal +ai
ai ~ N(0, 1.32^2)
The coefficients:
Random effects:
  Groups        Name        Variance Std.Dev.
  stationNumber (Intercept) 1.702    1.324
Number of obs: 72, groups:  stationNumber, 72

Fixed effects:
             Estimate Std. Error z value Pr(>|z|)
(Intercept)  20.5694    12.6924   2.182  0.00146 **
Temp          1.1716     0.2222   3.823 2.41e-05 ***
Sal          -2.1222     0.3710  -6.450 4.04e-05 ***

- For the other GLMM (glmer.nb(Zooplankton ~ offset(filtered volume) +  
Light * Depth + (1|stationNumber), data)), how can I generate the  
equation? What to put as offset?
The coefficients are:
Random effects:
  Groups  Name        Variance Std.Dev.
  Station (Intercept) 1.865    1.365
Number of obs: 102, groups:  Station, 51

Fixed effects:
                             Estimate Std. Error  z value Pr(>|z|)
(Intercept)                 -2.31986    0.53036 -32.290  < 2e-7 ***

Many thanks in advance for your time and help,
All the best!
