add_random(subj = 4, item = 2) %>%
add_between("subj", condition = c("cntl", "test")) %>%
add_between("item", version = c("A", "B"))
#> # A tibble: 8 × 4
#> subj item condition version
#> <chr> <chr> <fct> <fct>
#> 1 subj1 item1 cntl A
#> 2 subj1 item2 cntl B
#> 3 subj2 item1 test A
#> 4 subj2 item2 test B
#> 5 subj3 item1 cntl A
#> 6 subj3 item2 cntl B
#> 7 subj4 item1 test A
#> 8 subj4 item2 test B
