This doesn't add arrows to the ends of lines:

require(igraph)
gr <- make_graph('bull')
E(gr)$class <- sample(letters[1:3], gsize(gr), replace = TRUE)
V(gr)$class <- sample(letters[1:3], gorder(gr), replace = TRUE)

ggraph(gr, 'igraph', algorithm = 'nicely') +
  geom_edge_link(arrow = grid::arrow(length = unit(0.5, "cm")))
