Bayesian Network with R

Question

I am trying to build a Bayesian network model. However I am unable to install a suitable package. Tried gRain, bnlearn and Rgraphviz for p

Answer 1

For R version 3.5 or greater, you can install Bioconductor packages using BiocManager.
Please see: https://bioconductor.org/install.
I installed them using the following code:

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")
BiocManager::install(version = "3.10")
BiocManager::install(c("gRbase", "RBGL", "Rgraphviz", "gRain"))

Answer 2

The packagesgraph, RBGL and Rgraphviz are not on CRAN but on bioconductor.

To install these packages, execute

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")
BiocManager::install(c("graph", "RBGL", "Rgraphviz"))

Then install the packages from CRAN in the usual way:

install.packages("gRain", dependencies=TRUE)
