gc

Boolean, if 'TRUE' (default) then the giant component is extracted, if 'FALSE' then the whole graph is returned

from <- c("1", "2", "4")
to <- c("2", "3", "5")
edges <- data.frame(from = from, to = to, stringsAsFactors = FALSE)
nodes <- data.frame(name = c("1", "2", "3", "4", "5"), stringsAsFactors = FALSE)
df_to_graph(edges, nodes)
