sienaDataConstraint: Function to change the values of the constraints between networks.

Description

This function allows the user to change the constraints of "higher", "disjoint" and "atLeastOne" for a specified pair of networks in a Siena data object.

Usage

sienaDataConstraint(x, net1, net2,
          type = c("higher", "disjoint", "atLeastOne"), value = FALSE)

Value

Updated Siena data object.

Arguments

x

Siena data object; maybe a group object?

net1

name of first network

net2

name of second network

type

one of "higher", "disjoint", "atleastOne". Default is "higher".

value

Boolean giving the value.

Author

Examples

nowFriends <- sienaDependent(array(c(s501, s502, s503), dim=c(50, 50, 3)))
ever <- array(c(s501, s502, s503), dim=c(50, 50, 3))
ever[,,2] <- pmax(ever[,,1], ever[,,2])
ever[,,3] <- pmax(ever[,,2], ever[,,3])
everFriends <- sienaDependent(ever)
# Note: this data set serves to illustrate this function,
# but it is not an appropriate data set for estimation by siena07,
# because everFriends (for the three waves together) depends deterministically
# on nowFriends (for the three waves together).
nowOrEver <- sienaDataCreate(nowFriends, everFriends)
attr(nowOrEver, "higher")
nowOrEver
nowOrEver.unconstrained <-
   sienaDataConstraint(nowOrEver, everFriends, nowFriends, "higher", FALSE)
nowOrEver.unconstrained
attr(nowOrEver.unconstrained, "higher")
