please write an example code using 'lme4' function for a logistic regression model analysis. Dependent variable is a categorical variable with 3 levels, fixed effect independent variable has 4 levels, and random factor has 2 levels. this analysis should be applied on each subject

library(lme4)
 
# data
data <- read.table("http://www.stat.ufl.edu/~aa/social/data/nlswork.dat", sep="", 
                   header=T, na.strings=".")
 
# logistic regression model
model <- glmer(union ~ educ + (1|id), data=data, family="binomial")
summary(model)
