I have a generalized linear model (family - gamma) with interaction, and need to plot it specifically in ggplot2 (on a response scale). The model was constructed with following code:

fit1mult = glm(SIZE_OOCYTE ~ TREATMENT * CASTE, 
               family = Gamma(link = "log"), data=data1)

I made a plot using the lattice package, and it looks like this:

effect plot How can I make a similar one in ggplot? I know that the geom_smooth has an option glm, but don't know how to apply it.

Thanks in advance for suggestions!

UPD. Solution:

library(ggeffects)

 mydf1 <- ggpredict(fit1mult, terms = c("CASTE", "TREATMENT"))

 plot(mydf1)

Result: new plot
