r中lme4的相互作用图

Question

我想在多级模型中绘制两个连续变量的交互效果。该模型如下：

lme4::glmer(final$trust ~ final$educ.c + 
final$age.c + 
final$gender + 
final$C14 RESPONDENT_OCCUPATION_SCALE + 
final$tot_country.c + 
final$int_use.c + 
final$educ.c*final$acc.c + 
(final$educ.c | final$Country), 
data = final, 
family = binomial, 
weights = final$W85_WEIGHT_EU27_+_TR_+_HR_+_NO_+_CH_+_IS, nAGQ=0, 
control = glmerControl(optimizer = "optimx", calc.derivs = FALSE, optCtrl = list(method = "nlminb", starttests = FALSE, kkt = FALSE)))

我感兴趣的互动是final$educ.c*final$acc.c，因变量是二分的，在咨询了各种网站和类似问题后，我仍然在努力解决它。有人有关于如何做的建议吗？
