R/igraph is an R package of the igraph network analysis library.

You can install the stable version of R/igraph from CRAN:

install.packages("igraph")

For the development version, you can use R-universe

options(
  repos = c(
    igraph = 'https://igraph.r-universe.dev',
    CRAN = 'https://cloud.r-project.org'
  )
)
install.packages('igraph')

or Github, with the pak package:

pak::pak("igraph/rigraph")

When compiling from sources, make sure that you have C, C++ and Fortran compilers, as well as development packages for glpk and libxml2. On Debian/Ubuntu, use apt install libglpk-dev libxml2-dev. On Fedora, use yum install glpk-devel libxml2-devel.

For installation from source on Windows, you need to have RTools installed. For versions R >= 4.0 you can install the dependencies using:

pacman -Sy mingw-w64-{i686,x86_64}-glpk mingw-w64-{i686,x86_64}-libxml2

See the Installation FAQ.

See the igraph package's website for the complete manual.

A good entry point is the "Get started" vignette, in English or Spanish.

For an overview of igraph's functionality see the reference index. It includes experimental functions on which we especially welcome feedback (but feedback on any function is appreciated)!
