Need your help on R & BioC exploration

I have just finished a graduate introductory R & BioC class, and found
them very interesting.   At this moment, I am not doing any R & BioC
related-work, which might end up with "use it or lose it".   My plan
is to get into bioinformatics fields shortly after the completion of
master's degree in bioinformatics that I am studying.  Considering
being very new to R & BioC, I think there might be some projects,
group study, work, workshop, etc that I can participate and learn R &
BioC.

Please let me know if you know of anything helpful for my exploration.  

Thank you,

Daniel
