[R] Problem with r project in ubuntu xenial

[George Balas]

For anyone who sees this conversation.

There is a bug in installation of igraph in R language in Ubuntu. There is
a solution in stackoverflow. We have to use the devtools. Write this code:
install.packages("devtools")
library(devtools)
install_github("igraph/rigraph")

If there are errors installing devtools just install any package that
comments.
