showInteraction {mgm} | R Documentation |
Retrieving details of interactions
Description
Retrieves details of a specified interaction from mgm model objects.
Usage
showInteraction(object, int)
Arguments
object |
The output of one of the estimation functions |
int |
An integer vector specifying the interaction. For mVAR models, this vector has length 2. For MGMs the vector can be larger to request details of interaction of order > 2. |
Details
Currently the function only returns details of pairwise interactions from output objects of mgm()
.
Value
variables |
Integer vector returning the variables specified via the argument |
type |
Character vector returning the type of the specified variables variables |
level |
Integer vector returning the number of levels of the specified variables variables |
parameters |
A list of length equal to the order k of the specified interaction. The entries contain the set of parameters obtained from the nodewise regressions on the k variables. Depending on the type of the variables in the interaction, these sets can obtain one or several parameters. For details see |

Examples
## Not run:
## We fit a pairwise and 3-order MGM to the mixed Autism dataset (?autism_data)
# 1) Fit Pairwise MGM
# Call mgm()
fit_d2 <- mgm(data = autism_data$data,
type = autism_data$type,
level = autism_data$lev,
k = 2) # ad most pairwise interacitons
# Weighted adjacency matrix
fit_d2$pairwise$wadj # for instance, we see there is an interaction 1-2
# 2) Look at details of interaction 1-2
showInteraction(object = fit_d2,
int = c(1, 2))
