Description Usage Arguments Value See Also Examples

Provides a way to create an object as a "item_matrix".

1	item_matrix(x)

`x`	Either a `data.frame` or `matrix`.

A item_matrix object.

as_item_matrix()

# Item matrix values
x = matrix(c(1, 0, 0, 1, 1, 1), ncol = 2)

# Item matrix initialization
items = item_matrix(x)

# View item matrix
items

# Data Frame encoding of items
items_df = data.frame(
   s1 = c(1, 0, 1, 1, 0, 1),
   s2 = c(0, 1, 0, 1, 1, 0)
)

# Create an Item Matrix
items = item_matrix(items_df)

# View item matrix
