gmodel.preset function

Generate one of pre-specified graphons.

gmodel.preset generates one of pre-specified graphons of size $(n \times n)$. Users can select one of 10 different graphons by their id, an integer from 1 to 10. The table of available graphons follows that of the reference article given below.

gmodel.preset(n, id = 1, sort = TRUE)

Arguments

• n: the number of nodes for a graphon to be generated.
• id: an integer from 1 to 10, each corresponding to a specific graphon model.
• sort: a logical value; TRUE to sort in an decreasing order of degree, FALSE otherwise.

Returns

an $(n\times n)$ graphon matrix.

Examples

## Not run:

## Generate 3 random graphons of nodal size 100.
n  = 100
r3 = (sample(1:10,3))
W1 = gmodel.preset(n,id=r3[1])
W2 = gmodel.preset(n,id=r3[2])
W3 = gmodel.preset(n,id=r3[3])

## Generate corresponding observations and plot them
A1 = gmodel.P(W1)
A2 = gmodel.P(W2)
A3 = gmodel.P(W3)

\dontshow{
 for (i in 1:10){
   W = gmodel.preset(100,id=i)
 }
}
## End(Not run)
