greedy_vertex_coloring issue

[yli223]

I am trying to use greedy_vertex_coloring function for my research, but it does not work. Here is my version:

R: R 4.1.0 GUI 1.76 High Sierra build (7976)
iGraph: igraph_1.3.5

Here is my command:

library(igraph)
g <- make_graph("petersen")
greedy_vertex_coloring(g)

Here is my output:

Error in greedy_vertex_coloring(g) :
could not find function "greedy_vertex_coloring"

Anyone knows what is happening here? Thank you in advance for your help!

What is the output of sessionInfo()?

Oh, after updating R and reinstalling the igraph library, it works now. Thanks!
