Function to convert an igraph from one or two tibbles

Description

xTB2IG is supposed to convert an igraph from one or two tibbles.

Usage

xTB2IG(edges, nodes = NULL, directed = FALSE, intersected = NULL)

Arguments

edges	a tibble or data frame for edge attributes
nodes	a tibble or data frame for node attributes. It can be NULL
directed	a logic specifying whether to create a directed graph. By default it is false
intersected	a logic or NULL specifying whether to restrict to only the intersected vertices (from input nodes and edges). By default it is NULL; it will be forced true (if the input nodes do not contain all vertices in the input edges); however, the input nodes can contain vertices not in the input edges. It only works when the input nodes are not NULL

Value

an igraph object

Note

none

Examples

set.seed(825)
ig <- sample_pa(20)
V(ig)$name <- seq(1,vcount(ig))
ig %>% xIG2TB('edges') -> edges
ig %>% xIG2TB('nodes') -> nodes

xTB2IG(edges, nodes) -> g

# nodes do not cointain all vertices in the edges
nodes[1:10,] -> nodes2
xTB2IG(edges, nodes2) -> g2
