Hi,

Did you try to install the package with devtools?

devtools::install_github("gaborcsardi/pkgconfig")
devtools::install_github("igraph/rigraph")

This is the developmental version. devtools will deal better with the missing dependencies. From the error that you've posted, it seems that you don't have qgraph installed. So, installing this package before trying to install igraph might solve the issue. Although you might get other errors related with other missing packages. Try with devtools and let me know if worked.

Installation goes fine but loading the library returns error

[antonioggsousa]

Yes, I see the problem qgraph requires R version less than 4.0.2. So, it can not load the package.

Can you try to load the qgraph package: library(qgraph). If the error persists, try to install this package with the development version through devtools: devtools::install_github("SachaEpskamp/qgraph").
