[BioC] getBioC and R configuration problem

[Ron Ophir]

Dear All,
I installed R on linux red-hat 7.3. I tried to run getBioC() script, which download R packages from bioconductor site, but I get the followin error message:

Error in getBioC() : Your R is not currently configured to allow HTTP
connections, which is required for getBioC to work properly.

How do I configure R correctly?

Thanks,
Ron
