Examples

mycovs <- list(batch = sample(c(0, 1), 6, replace = TRUE),
array = as.factor(sample(c('a', 'b', 'c'), 6, replace = TRUE)),
day = sample(c(0, 1, 3), 6, replace = TRUE))
des_mat <- const.mod(mycovs)
print(mycovs)
#> $batch
#> [1] 0 1 1 0 1 0
#> 
#> $array
#> [1] a b a a a b
#> Levels: a b
#> 
#> $day
#> [1] 0 0 3 0 0 0
#> 
print(des_mat)
#>   batch array.a array.b day
#> 1     0       1       0   0
#> 2     1       0       1   0
#> 3     1       1       0   3
#> 4     0       1       0   0
