Function to construct multilevel networks from multimodal structures.
mlvl(x = NULL, y = NULL, type = c("bpn", "cn", "cn2", "list"), symCdm,
diag, lbs)An object of ‘Multilevel’ class of chosen type.
the multilevel network
(list) domain and codomain labels
a vector indicating the domain of the data in mlnet where 1M is for domain and 2M is for the codomain.
domain data
codomain data
type of multilevel system:
bpn for binomial projection
cn for common membership network
cn2 for co-affiliation of network members
list for the multimodal structures as a list
(optional and logical, only for bpn) whether or not symmetrize the codomain structure
(optional and logical) whether or not include the entries in the diagonal matrices
(optional, only for cn2) tie labels

The default multilevel system is a binomial projection bpn that requires data for the two domains, as with
cn2 as well.
Option cn does not need the domain in “x” since returns the co-affiliation of network members from the codomain structure.
Since these are different components in the multilevel system for co-affiliation of network members,
it is possible to specify the domain and codomain labels in lbs as a list object.
Making symmetric the codomain structure with symCdm is many times convenient for visualization purposes.

# array for the domain
arr1 <- round( replace( array(runif(18), c(3,3,2)), array(runif(18), c(3,3,2))>.9, 3 ) )
# rectangle array for the co-domain
arr2 <- round( replace( array(runif(12), c(3,2,2)), array(runif(12), c(3,2,2))>.9, 3 ) )
# multilevel system with default type
mlvl(arr1, arr2)
