Examples

# Q matrix values
x = matrix(c(1, 0, 0, 1), nrow = 2)

# Q matrix wrapper
q_mat = q_matrix(x)

# View the converted Q matrix
q_mat

#> A q matrix: 2 x 2 
#> Strictly Identified: 
#> No.
#> Generically Identified: 
#> No.
#>       Trait1 Trait2
#> Item1      1      0
#> Item2      0      1

# Data Frame encoding of Q
q_df = data.frame(
   k1 = c(1, 0),
   k2 = c(0, 1)
)

# Create a Q matrix
q_mat = q_matrix(q_df)
