\title{Get interaction from database}
\usage{
get_interaction_from_database(X, db = NULL, type = "db", user.ego = FALSE)
}
\arguments{
\item{X}{vector of nodes or list of vectors}

\item{db}{data.frame (with two columns: from, to) or igraph}

\item{type}{character added to node metadata}

\item{user.ego}{logical, if user.ego == TRUE looks for first degree neighbors
in db and add 'mode' metadata ('core'/'extended')}
}
\value{
a subset graph of db from X list of nodes
}
\description{
Returns an interaction graph from a vector of nodes (or a list of vectors)
and an interaction database (data.frame or igraph)
}
\examples{
X <- letters[1:4]
db <- as.data.frame(list(from = sample(letters[1:10], replace = TRUE),
                         to = sample(letters[1:10], replace = TRUE)))
                         
 sub <- get_interaction_from_database(X, 
                                      db)
 
 db.graph <- igraph::graph_from_data_frame(db, 
                                           directed=FALSE)
 sub <- get_interaction_from_database(X, 
                                      db)
