How to construct Bayesian regulatory network in R with gene expression profile

Question

[sugus]

Hi guys, Recently I was working on a number of cancers with histological studies. I obtained gene expression profiles for some cancers and completed the calculation of differential expression and construction of coexpression networks, which are collaborative networks. Now I would like to build some regulatory network, using Bayesian approach, and how to make it happen with expression data in R? Could anyone knowing about it share me more details with any code you have. Thank you very much.
