Examples

library(lme4) data(sleepstudy) # prepare some data... sleepstudy$mygrp <- sample(1:5, size = 180, replace = TRUE) sleepstudy$mysubgrp <- NA for (i in 1:5) { filter_group <- sleepstudy$mygrp == i sleepstudy$mysubgrp[filter_group] <- sample(1:30, size = sum(filter_group), replace = TRUE) } m <- lmer( Reaction ~ Days + (1 | mygrp / mysubgrp) + (1 | Subject), data = sleepstudy )
#> boundary (singular) fit: see ?isSingular
head(get_random(m))
#> mysubgrp mygrp Subject #> 1 6 3 308 #> 2 10 1 308 #> 3 26 2 308 #> 4 30 2 308 #> 5 15 4 308 #> 6 15 2 308
