Package is actually only available on github :
devtools::install_github("datastorm-open/DependenciesGraphs")For use directly in R, you must first load package(s) using library function :
library("ibr")# Prepare data
dep <- envirDependencies("package:ibr")
# visualization
plot(dep)# Prepare data
dep <- funDependencies("package:ibr","iterchoiceS1")
# visualization
plot(dep)launch.app()
